[0048] As illustrated in FIGS. 1 to 18, the electric power generation system according to the present embodiment includes a starting power generation unit (100) that generates and stores starting power, a power generation control unit (200) that controls power generation based on the generated starting power, a power generation unit (300) that performs power generation according to a control signal of the power generation control unit (200), an output unit (400) that outputs power from the power generation unit (300), and a feedback unit (00) that receives feedback on the generated power and provides it to the starting power generation unit (100).
[0049] The electric power generation system of the present embodiment generates power using the starting power of the starting power generation unit (100) and the power generated by the power generation unit (200) is output to the outside and can also be fed back and used as starting power. Through this, power generation can continue even when starting power is not generated by the starting power generation unit (100).
[0050] The starting power generation unit (100) includes a power generation unit (110) that generates its own power using eco-friendly energy, a starting battery unit (120) that stores the generated power, a power input unit (130) that receives feedback power from a feedback unit (500), and a starting power control unit (140) that provides the power generated by the power generation unit (110) or the power provided through the power input unit (130) to the starting battery unit (120) or to the power generation control unit (200).
[0051] For the power generation unit (110) of this example, it is effective to generate power using sunlight.
[0052] The power generation unit (110) includes a solar panel module (111) that produces power using solar energy, a power induction module (112) that induces power generated by the solar panel module (111), and a power output module (113) that outputs the induced power.
[0053] It is effective for the solar panel module (111) to include a number of solar cells. The solar panel module (111) has flexible characteristics, and it is effective to attach it to various spaces to generate electricity through solar power. Of course, it is not limited to this, and it is preferable for the solar panel module (111) to be manufactured in the form of a multi-sided plate and fixedly installed in a certain space.
[0054] The power induction module (112) may include a junction box that connects a solar panel module (111) having a plurality of solar cells and collects the power produced from them. The power induction module (112) may also include a function to amplify the power of the solar panel module (111) or convert it to a certain level.
[0055] The power output module (113) is effective for outputting the starting power generated from the solar panel module (111) to the outside. It is preferable to use an output terminal for the power output module (113), and it is preferable that the output terminal be directly connected to the starting power control unit.
[0056] In this example, it is effective for the power generation unit (110) to supply power for starting the power generation unit (300). In addition, it is effective to use solar power generation with the power generation unit (110) to generate power from sunlight on a daily basis. Of course, it is desirable to perform power generation for 3.5 to 5 hours per day. In this example, it is effective to produce 20 to 100W of power. Of course, it is not limited to this, and it is effective to adjust the power generation capacity by increasing or decreasing the number of solar cells in the solar panel module (111) according to the power generation capacity desired by the user.
[0057] In this example, power generation can be performed continuously for 20 to 24 hours when power generation is possible for a maximum of 5 hours per day using solar power. Through the power generation unit (300) of this example, power can be produced at a minimum of 300 to 500 Wh in the case of a house, and the amount of power generated can vary depending on the location of use. Power generation can be achieved using one-third of the solar panels compared to conventional solar power generation.
[0058] Of course, the power generation unit (110) is not limited to this, and depending on the region where the system is located, it is possible to generate power using wind, hydroelectric, or geothermal energy as the power generation unit (110).
[0059] It is effective for the starting battery unit (120) to store the starting power generated by the power generation unit (110) and the feedback power provided through the power input unit. It is effective for the starting battery unit (120) to receive the starting power generated by the starting power generation unit (110) from the starting power control unit (140) or to receive and store the feedback power from the power input unit (130). Additionally, the starting power stored in the starting battery unit (120) by the starting power control unit (140) can be provided to the power generation control unit (200).
[0060] It is desirable for the starting battery unit (120) to store the starting voltage supplied from sunlight and to supply power for operating the power generation unit (300). Since the operating time from sunlight may be insufficient, charging by a recharge system up to 1 to 40% of the power generation capacity generated by the power generation unit (300) can be used for operating the power generation unit. Preferably, charging by a recharge system up to 5 to 30% of the power generation capacity may also be performed.
[0061] In addition, since the amount of power generated by solar energy is insufficient, feedback power received from the power generation unit (300) through the power input unit (130) can be stored and supplied as power for operating the power generation unit (300).
[0062] In this example, various types of batteries can be used as the starting battery unit (120). Of course, it is not limited to this, and it is also possible to use various devices capable of storing power (e.g., batteries) as the starting battery unit (120). In this example, it is possible to use a supercapacitor as the starting battery unit (120). It is effective for the supercapacitor to include two electrodes, an electrolyte, and a separator. The supercapacitor has high energy density and can have fast charging and high output density. The supercapacitor can be charged even at low currents. For example, it can be charged with a current within the range of 10 to 300 mA. As a result, when the power generation unit generates power using a solar panel, the output current may be very low if there is insufficient sunlight. Consequently, while a general battery may not be able to be charged, a supercapacitor can be charged. This makes it possible to store starting power generated in a bad environment. Of course, it is also effective to use both a battery and a supercapacitor as the starting battery unit (120).
[0063] The power input unit (130) has an input terminal connected to the feedback unit (500) to receive feedback power from the feedback unit (500). Additionally, the power input unit (130) can provide the received feedback power to the starting battery unit (120) to charge the starting battery unit (120). Furthermore, the power input unit (130) is equipped with a separate control switch or control module, and it is effective for this control module to be operated by the starting power control unit (140) to transmit feedback power to the starting battery unit (120). Through this, feedback power may or may not be provided to the starting battery unit (120) depending on the control signal of the starting power unit (110).
[0064] Additionally, the output terminal of the power input unit (130) can be connected to the starting battery unit (120) and simultaneously connected to the power generation control unit (200). Through this, it may be possible to directly transmit feedback power to the power generation control unit (200) according to the control signal of the starting power control unit (140).
[0065] The starting power control unit (140) effectively provides the starting power generated by the power generation unit (110) or the feedback power provided through the power input unit to the starting battery unit (120) or to the power generation control unit (200). The starting power control unit (140) may provide the starting power generated by the power generation unit (110) to the starting battery unit (120) or to the power generation control unit (200), or provide the feedback power from the power input unit (130) to the starting battery unit (120), through control of a separate switching means or component. Not limited thereto, the starting power control unit (140) may also provide the starting power or feedback power to the starting battery unit (120) and the power generation control unit (200) simultaneously. In this case, the starting power control unit (140) may be able to divide the amount of the starting power or feedback power, thereby enabling power to be provided to both sides.
[0066] Additionally, the starting power control unit (140) provides the stored power stored in the starting battery unit (120) to the power generation control unit (200). In this way, when starting power is generated by the power generation unit (110) or when the generated starting power is insufficient, it is desirable to provide the starting power stored in the starting battery unit (120) to the power generation control unit (200). This is because sufficient power can be provided to charge the starting battery unit (120) through the power input unit (130).
[0067] To this end, the starting power control unit (140) can check the status of the power generation unit (110), the starting battery unit (120), and the power input unit (130), and perform a control operation based on this, or include a module or component for performing a control operation.
[0068] The starting power control unit (140) can check the operating status of the power generation unit (110). To this end, the starting power control unit (140) can check whether the solar panel, i.e., the solar cell of the power generation unit (110), is operating normally. That is, it is desirable to check the output power of the solar cell and compare it with a reference setting value to check whether it is operating normally. At this time, it is desirable that the reference setting value be the minimum value for operating the power generation control unit (200). If the starting power generated by the power generation unit (110) is lower than the reference setting value, it is effective for the starting power control unit (140) to provide it to the starting battery unit (120) to charge the starting battery unit (120). As a result, even if the output of the power generation unit (110) is not sufficient to start the power generation control unit (200), it can be utilized for battery charging. That is, if the amount of power from the power generation unit (110) is insufficient, the feedback power from the power input unit (130) can be utilized.
[0069] The starting power control unit (140) can check the charging status of the starting battery unit (120) and, based on this, output the charging or power stored in the starting battery unit (120) to the outside, i.e., the power generation control unit (200). The starting power control unit (140) stores information regarding the starting battery unit (120), such as charging capacity, and it is desirable to detect the charging status. At this time, the charging of the starting battery unit (120) can be performed using the feedback power of the power input unit (130).
[0070] In addition, charging can be performed by distinguishing between various batteries, and safety can be improved by adjusting the charging amount according to the external temperature.
[0071] The power generation control unit (200) includes a power generation conversion unit (210) that converts the power generation unit (100)'s power generation unit, an operation control unit (220) that generates a control signal to control the operation of the power generation unit (300), a control output unit (230) that outputs the control signal to the power generation unit (300), and an input display unit (240) that displays the power generation unit (110)'s power generation unit.
[0072] It is effective for the starting power converter (210) to convert the DC power of the starting power generator (100). It is effective for the starting power converter (210) to convert the voltage of the DC starting power of the starting power generator (100), and to convert it to 12 to 1200V. It is desirable to convert it to 12 to 96V for household or general use, to 96 to 500V for use in manufacturing facilities, and to step up the voltage to 500 to 1200V for use in places requiring a larger amount of generated power.
[0073] It is preferable to use a DC-DC step-up converter as the starting power converter (210). It is possible to use a buck converter, a boost converter, a buck-boost converter, etc. as the starting power converter (210).
[0074] It is effective for the operation control unit (220) to generate a control signal that controls the RPM or rotational conversion of the power generation unit (300) according to the control of a user or manager. It is effective for the operation control unit (220) to generate three control signals and provide them to the power generation unit (300).
[0075] The operation control unit (220) may be able to control the amount of power generated by adjusting the RPM of the power generation unit (300) through a separate input or circuit configuration, and may be able to adjust the rotation direction of the power generation unit (300). In this example, it is effective to control the RPM through a control volume that controls rotation and to control left and right rotation through a separate switch.
[0076] For the switch to control left and right rotation, it is effective to be a switch that switches rotation to reduce the load in the rotational state when the wind direction is opposite when the blade is mounted.
[0077] The input voltage can be supplied to the generator control via the control input voltage, passing through an indicator displaying the supply voltage, current usage, power consumption, and total usage before being supplied to the generator control through the control boost converter.
[0078] The operation control unit (220) can receive the current voltage for starting the power generation unit (300) through the starting power conversion unit (210). That is, it can receive DC power through a boost converter, i.e., an input voltage control.
[0079] The operation control unit (220) converts the provided DC starting power into AC to generate a control signal. The operation control unit (220) can convert to AC through a built-in link inverter circuit and can provide this converted control signal to the power generation unit (300) through the control output unit (230).
[0080] It is effective for the control output unit (230) to generate a control signal through the operation control unit (220). At this time, it is preferable for the control signal to have a three-phase signal. It is effective for the first to third control signals to each have the same waveform and for their phases to be different from each other.
[0081] The control output unit (230) comprises a first output terminal (out1) that outputs a first control signal, a second output terminal (out2) that outputs a second control signal, a third output terminal (out3) that outputs a third control signal, a first transistor (T1) and a 10th diode (D10) connected in parallel between a positive voltage terminal and the first output terminal (out1), a second transistor (T2) and a 20th diode (D20) connected in parallel between a positive voltage terminal and the second output terminal (out2), a third transistor (T3) and a 30th diode (D30) connected in parallel between a positive voltage terminal and the third output terminal (out3), a fourth transistor (T4) and a 40th diode (D40) connected in parallel between a negative voltage terminal and the second output terminal (out2), a fifth transistor (T5) and a 50th diode (D50) connected in parallel between a negative voltage terminal and the third output terminal (out3), and a third transistor connected in parallel between a negative voltage terminal and the first output terminal (out1). It is effective to include a connected sixth transistor (T6) and a sixth diode (D60), wherein the first output terminal (out1) is connected to the first control signal terminal of the operation control unit (220), the second output terminal (out2) is connected to the second control signal terminal of the operation control unit (220), and the third output terminal (out3) is connected to the third control signal terminal of the operation control unit (220).
[0082] The input display unit (240) is positioned between the starting power conversion unit (210) and the operation control unit (220) to calculate and display the input power effectively. Through this, it is desirable to check the amount of power input to the power generation unit (300) in real time.
[0083] In the power generation unit of this embodiment, the current voltage for starting it is supplied as DC power to the power generation control unit, i.e., the power generation control, through an input voltage controller, i.e., a starting power control unit. At this time, it is converted to AC through a control-integrated link inverter circuit, and this converted AC can be supplied to the power generation unit, i.e., the generator power. The electricity, i.e., power generated by the generator, can be converted to DC through a circuit such as a bridge diode and supplied to the inverter. At this time, due to the phase difference between the input and output, mutual collision between the input and output can not occur.
[0084] The power generation unit (300) includes an input / output unit (310) that receives a control signal from the power generation control unit (200) and outputs power generated by the power generation unit (320), and a power generation unit (320) that generates power based on the control signal.
[0085] The input / output unit (310) includes an input / output connection unit (311) that receives a three-phase control signal and outputs three-phase power generation, and a power generation output unit (312) that converts and outputs the power generation of the input / output connection unit (311).
[0086] The power generation unit (300) is combined into multiple windings from the internal winding, and six wires can be output by connecting the remaining windings other than the combined windings. Through this, Y-connection or D-connection can be performed. This allows the connection method to be changed differently depending on the amount of power generated or the conditions of the installation site. At this time, if a blade or propeller is mounted on the power generation unit (300) and used, the rotational speed changes according to an external force, namely wind, and it can be easily used to increase or decrease the amount of power generated. That is, if the speed of the blade or propeller increases according to the strength of the wind, the input voltage decreases and the output can increase.
[0087] Of course, in this example, six lines are output from the power generation unit (300), but the present invention is not limited thereto, and it is possible to output two or more and 21 or fewer lines. Of course, it is effective to output six lines.
[0088] The input / output connection section (311) includes first to sixth connection input terminals (IT1 to IT6) connected to the power generation unit (320) side and first to sixth connection output terminals (OT1 to OT6) connected to the power generation output section (312) side.
[0089] The first to sixth connection input terminals (IT1 to IT6) are connected to the terminals of the power generation unit (320).
[0090] The first to sixth connection input terminals (IT1 to IT6) can each be connected to the first to sixth connection output terminals (OT1 to OT6).

[0091] It is effective for the first connection output terminal (OT1), the third connection output terminal (OT3), and the fifth connection output terminal (OT5) among the connection output terminals to be connected to each other.

[0092] The power generation output section (312) can convert power generation, i.e., AC voltage, into DC through a three-phase bridge diode structure.
[0093] Also, not limited thereto, the input / output connection section (311) includes first to sixth connection input terminals (IT1 to IT6) connected to the power generation unit (320) side and first to sixth connection output terminals (OT1 to OT6) connected to the power generation output section (312) side.
[0094] The first to sixth connection input terminals (IT1 to IT6) are connected to the terminals of the power generation unit (320).
[0095] The first to sixth connection input terminals (IT1 to IT6) can each be connected to the first to sixth connection output terminals (OT1 to OT6). That is, the first connection input terminal (IT1) can be connected to the first connection output terminal (OT1), the second connection input terminal (IT2) can be connected to the second connection output terminal (OT2), the third connection input terminal (IT3) can be connected to the third connection output terminal (OT3), the fourth connection input terminal (IT4) can be connected to the fourth connection output terminal (OT4), the fifth connection input terminal (IT5) can be connected to the fifth connection output terminal (OT5), and the sixth connection input terminal (IT6) can be connected to the sixth connection output terminal (OT6).
[0096] Among the connection output terminals, the first and second connection output terminals (OT1, OT2) are connected to each other and can be connected to the first external input terminal of the power generation output unit (312). Additionally, the third and fourth connection output terminals (OT3, OT4) are connected to each other and can be connected to the second external input terminal of the power generation output unit (312). The fifth and sixth connection output terminals (OT5, OT6) are connected to each other and can be connected to the third external input terminal of the power generation output unit (312).
[0097] Of course, the present embodiment is not limited thereto, and various structures and connection methods can be applied to the connection of the input / output connection part (311).
[0098] The power generation output section (312) comprises first to third external input terminals (E_IN1 to E_IN3), first and second external output terminals (E_OUT1, E_OUT2), a first diode (D1) connected between the first external input terminal (E_IN1) and the first node (N1), a second diode (D2) connected between the second external input terminal (E_IN2) and the first node (N1), a third diode (D3) connected between the third external input terminal (E_IN3) and the first node (N1), a first resistor (R1) and a first inductor (L1) connected in series between the first node (N1) and the first external output terminal (E_OUT1), a fourth diode (D4) connected between the first external input terminal (E_IN1) and the second external output terminal (E_OUT2), and between the second external input terminal (E_IN2) and the second external output terminal (E_OUT2). It includes a connected fifth diode (D5) and a sixth diode (D6) connected between the third external input terminal (E_IN3) and the second external output terminal (E_OUT2).
[0099] The cathodes of the first to third diodes (D1 to D3) are connected to the first node, and the anodes of the fourth to sixth diodes (D4 to D6) are connected to the second external output terminal. Through this, it is possible to allow current to flow in a certain direction through the first to sixth diodes (D1 to D6). Through this, AC voltage can be rectified and output as DC.
[0100] Through this, the input / output terminals become capable of outputting AC power as DC power.
[0101] The power generation unit (320) includes a rotating part (321) that rotates, a fixed part (322) located between the rotating part (321) and generating power, a housing part (323) that covers the rotating part (321) and the fixed part (322), and a fixed output part (324) that outputs power from the fixed part (322).
[0102] The rotating part (321) includes a first rotating plate part (3211) located on one side with a plurality of grooves formed on the inside, a second rotating plate part (3212) installed on the other side to correspond to the first rotor with a plurality of grooves formed on the inside, a central axis part (3213) connected to the central axis of the first and second rotating plate parts (3211, 3212), a rotating fixing part (3214) that fixes the first and second rotating plate parts (3211, 3212) to the center, and a plurality of magnet parts (3215) located in the plurality of inner grooves of the first and second rotating plate parts (3211, 3212).
[0103] It is effective for the first rotating plate part (3211) to include a rotating body in the shape of a circular plate, a rotating through hole provided in the central axis region of the rotating body, and a plurality of mounting grooves provided in the edge region of the inner surface of the rotating body.
[0104] It is preferable that the rotating body be manufactured in the shape of a circular plate with a certain thickness.
[0105] The rotational through-hole is formed by penetrating the central axis of the rotating body. In this case, it is effective to provide the rotational through-hole in a semi-circular shape. This enables the two rotating plates to transmit rotational force to each other via the central axis. If the through-hole is formed in a circular shape, the rotating plates may be separated from the central axis, preventing the rotational force from the central axis from being transmitted to the rotating plates, or conversely, preventing the rotational force from the rotating plates from being transmitted to the central axis. In this example, it is preferable to manufacture the rotational through-hole in a semi-circular shape with a portion of the circle cut off. Of course, it is not limited to this, and the shape of the rotational through-hole may be manufactured in a polygonal or elliptical shape.
[0106] The mounting groove is a space for mounting a plurality of magnet parts within the first rotating plate part (3211), and it is effective to form it on the inner side of the first rotating plate part, that is, on the inner surface adjacent to the rotating fixing part.
[0107] Here, it is preferable that the number of mounting grooves be an even number and be formed on the inner surface of the first rotating plate. Additionally, the mounting grooves may be of the same size and arranged at uniform intervals. It is preferable that the mounting grooves be arranged uniformly in a band shape along the edge region of the first rotating plate. Through such a structure, it is possible to uniformly arrange magnetic N and S as a pair, thereby forming a uniform magnetic field.
[0108] The depth of the mounting groove may vary depending on the thickness of the magnet being mounted, but in this example, it is effective to have a depth of 10 to 70 when the total thickness of the first rotating plate is 100. This makes it effective to ensure that the magnet mounted in the mounting groove forms a flat plane with the inner surface of the first rotating plate. This prevents problems caused by the magnet protruding during rotation and vortex phenomena caused by the magnet becoming concave.
[0109] Of course, the present invention is not limited thereto, and it is possible to make the magnet protrude above the inner surface of the first rotating plate or to make it recessed into the inner surface. In this case, if it protrudes, the height of the protrusion is set to within 1 to 20 mm from the inner surface of the first rotating plate to prevent issues caused by the protrusion and to bring the magnet closer to the fixing part. In addition, if it recesses, the height of the recess is set to within 1 to 10 mm from the inner surface of the first rotating plate to prevent issues caused by the recess and to allow the magnet to be stably positioned within the mounting groove.
[0110] It is preferable that the horizontal shape of the mounting groove be circular, as shown in the drawing. It is desirable that this shape accommodates a circular plate-shaped magnet. Of course, it is not limited to this, and it is possible to manufacture the mounting groove in a polygonal shape such as a triangle or a square. Through this, the magnetic field can be varied. Furthermore, it is not limited to this, and it is possible to form the mounting groove in a trapezoidal shape, such that the shorter side of the trapezoid is positioned close to the center of the first rotating plate. Through this, it is possible to increase the surface area of the magnet, and thereby adjust the strength of the magnetic field.
[0111] It is preferable that the center point of the first rotating plate (3211) be located in an area where the length of the straight line extending from the center point to the edge of the first rotating plate, passing through the center point of the first rotating plate (3211) and the center point of the mounting groove, is 100, and the center point of the mounting groove is located in an area where it is 50 to 90.
[0112] Here, if the mounting groove is located below the center point, that is, close to the center point, a disadvantage occurs in that the magnetic field produced by the magnet is concentrated in the center, and if the mounting groove is located above the center point, that is, close to the edge, a problem may occur in that the magnetic field produced by the magnet spreads widely outward. Preferably, the center point of the mounting groove can be located in an area of 60 to 80.
[0113] In the present invention, it is preferable that the mounting grooves be separated into three groups. These three groups may be arranged in a band-like shape in the edge area of the first rotating plate portion (3211). At this time, it is preferable that the number of mounting grooves located within these groups be equal. Additionally, it is effective for the spacing between the mounting grooves within the groups to be equal. Furthermore, the spacing between the groups may also be equal. The spacing between mounting grooves within the groups and the spacing between the groups may not be equal. It is effective for the spacing between the groups to be wider than the spacing between mounting grooves within the groups. Of course, it is not limited to this, and it is effective for the number of groups to be fewer or more than this.
[0114] It is effective for the second rotating plate part (3212) to include a circular plate-shaped rotating body, a rotating through hole provided in the central axis region of the rotating body, and a plurality of mounting grooves provided in the edge region of the inner side of the rotating body. The second rotating plate part (3212) may be formed symmetrically with respect to the first rotating plate part (3211). Of course, it is not limited thereto, and it is preferable for the second rotating plate part (3212) to be manufactured similarly or identically to the first rotating plate part (3211).
[0115] It is preferable that the number, location, and shape of the groups of the second rotating plate section be the same as those of the first rotating plate section.
[0116] The central shaft portion (3213) is preferably manufactured in a shape corresponding to the rotational through-holes of the first and second rotating plate portions (3211, 3212) and in a column shape with one side cut off. That is, the central shaft portion is preferably manufactured in a circular column shape, and its cross-section is preferably manufactured in a crescent shape, which is the shape of the rotational through-hole. Through this, the central shaft portion (3213) can rotate together with the first and second rotating plate portions (3211, 3212), making it possible to provide rotational force from one of the two plates to the other plate.
[0117] The rotation fixing part (3214) can fix the central shaft part (3213) and the first and second rotating plate parts (3211, 3212) so that they can rotate. It is preferable that the rotation fixing part (3214) has a first rotation fixing part that fixes the central shaft part (3213) and the first rotating plate part (3211), a second rotation fixing part that fixes the central shaft part (3213) and the second rotating plate part (3212), and a bearing part that supports the rotation of the central shaft part (3213).
[0118] It is preferable to firmly fix the central axis portion and the first and second rotating plate portions (3211, 3212) by adding a separate fixing member to the first rotating fixed portion and the second rotating fixed portion. This makes it possible for the first and second rotating plate portions (3211, 3212) to rotate relative to each other with respect to the central axis portion.
[0119] The bearing section is equipped with a plurality of bearings, and it is preferable that the central shaft portion penetrates through the inner center of the bearings. This makes it possible to fix and support the rotational force of the central shaft portion. At this time, it is preferable that a plurality of bearings be arranged in the space between the first rotating plate portion and the second rotating plate portion.
[0120] The magnet part (3215) includes a plurality of permanent magnets, and it is preferable that these permanent magnets be mounted in the mounting grooves of the first and second rotating plate parts (3211, 3212). Through this, it is preferable that the magnetic field of the magnets be changed according to the rotation of the first and second rotating plate parts (3211, 3212). In this example, it is preferable that the magnets of the first and second rotating plate parts (3211, 3212) have magnets of the same polarity located at the same location. Furthermore, it is not limited to this, and it is also preferable that magnets of different polarities be located at the same location. Of course, the center of the magnet of the first rotating plate part (3211) and the center of the magnet of the second rotating plate part (3212) may be arranged so as to be offset at an angle of 5 to 20 degrees. That is, based on a straight line extending in the same direction as the center axis (3213) from the center of the magnet of the first rotating plate (3211), the angle between the straight lines connecting the center of the magnet of the first rotating plate (3211) and the center of the magnet corresponding to the second rotating plate (3212) may be within the above range, i.e., 5 to 20 degrees.
[0121] Additionally, it is desirable that the magnets mounted on the first and second rotating plate sections (3211, 3212) have the same or similar magnetic force within an error range. Of course, this is not limited thereto, and it is possible for the magnetic force of the magnet mounted on the first rotating plate section (3211) to be greater than the magnetic force of the magnet mounted on the second rotating plate section (3212). Of course, conversely, the magnetic force of the magnet mounted on the second rotating plate section (3212) may be greater than the magnetic force of the magnet mounted on the first rotating plate section (3211). In this case, it is desirable for the magnitude of the magnetic force to differ within a range of 1.1 to 4 times.
[0122] The fixed part (322) is effectively configured such that a ferrite with a coil wound thereon is placed between the rotating part equipped with a rotating magnet, and the rotating part is rotated by power applied to the coil according to the control signal of the power generation control unit, and the power generated by the rotation of the rotating part is output through the coil.
[0123] The fixed portion (322) includes a first fixed plate portion (3221) positioned on one side, a second fixed plate portion (3222) positioned on the other side, a plurality of ferrite portions (3223) located between the first and second fixed plate portions (3221, 3222), and a coil portion (3224) wound on each of the plurality of ferrite portions (3223).
[0124] It is effective for the first fixing plate portion (3221) to include a square plate-shaped fixing body portion (3221a), a plurality of fixing groove portions (3221b) provided for fixing a ferrite portion (3223) at the edge of the fixing body portion (3221a), a fixing through-hole portion (3221c) provided in the central area of the fixing body portion (3221a), and a supporting through-hole portion (3221d) for supporting and fixing the fixing body portion (3221a).
[0125] It is effective to form a plurality of fixing grooves (3221b) in a circular band shape continuously in the fixed body part (3221a). At this time, the plurality of fixing grooves (3221b) in the circular band shape may be configured in two stages. That is, at this time, two circular band-shaped fixing grooves (3221b) with different diameters may be formed. For example, it is possible to arrange 10 to 50 fixing grooves in the shape of a circular band with a first diameter, and 10 to 40 fixing grooves (3221b) in the shape of a circular band with a second diameter smaller than the first. At this time, it is preferable that the plurality of fixing grooves (3221b) be spaced apart at a certain interval. Through this, a plurality of ferrites wound on a coil can be spaced apart at a uniform distance.
[0126] It is effective for the fixed through-hole portion (3221c) to have a central through-hole penetrating the center point of the fixed body portion (3221a) and a central through-hole having a diameter larger than the central through-hole. At this time, it is preferable that the central through-hole penetrates the central axis portion (3213) of the rotating portion (321) described above.
[0127] It is preferable that the support through-hole portion (3221d) be located at the four edges of the square-shaped fixed body portion (3221a), and that the two fixed plates be fixed in conjunction with the support through-hole portion (3222d) of the second fixed plate portion (322) by a separate fixed portion (322).
[0128] It is effective for the second fixing plate portion (3222) to include a square plate-shaped fixing body portion (3222a), a plurality of fixing groove portions (3222b) provided for fixing a ferrite portion (3223) at the edge of the fixing body portion (3222a), a fixing through-hole portion (3222c) provided in the central area of the fixing body portion (3221), and a supporting through-hole portion (3222d) for supporting and fixing the fixing body portion (3222a).
[0129] It is effective for the ferrite part (3223) to include a plurality of straight bar-shaped ferrites fixed by the first and second fixing plate parts (3221, 3222). It is effective to use various materials for the ferrite that can stably generate and maintain a magnetic field. In addition, it is effective for the ferrite part (3223) to be manufactured in the shape of a circular rod, with one side of the circular rod mounted in the fixing groove (3221b) of the first fixing plate part (3221) and the other side mounted in the fixing groove (3222b) of the second fixing plate part (3222) so that it is fixedly mounted between the two fixing grooves.
[0130] It is effective to select a ferrite by considering heat resistance, corrosion resistance, magnetism, and thermal stability, as well as magnetic flux density, coercivity, and magnetic flux holding power. For such ferrites, it is desirable to selectively use strontium (Sr) ferrite, barium (Ba) ferrite, MnZn ferrite, and NiZn ferrite.
[0131] Here, it is effective for the ferrite section (3223) to arrange multiple ferrites in groups so that they are distinguished from each other. That is, ferrites within a group are arranged adjacently, and ferrites are not arranged between the groups, and it is possible to make the spacing between the ferrites different.
[0132] Here, the group can be divided into 2 to 10 groups. In addition, it is desirable that the number of ferrites within each group be the same. Of course, this is not limited to this, and the number of ferrites may be different.
[0133] As previously described, the magnetic part (3215) of the rotating part (321) is also divided into groups, and it is preferable that the ferrite part is also divided into the same number of groups.
[0134] In this example, it is preferable that the ferrite section (3223) be divided into three groups. At this time, it is preferable that the number of ferrites located within the first to third groups be different from each other. Through this, it is preferable that the power produced through each group be different from each other.
[0135] It is effective for the coil section (3224) to include a plurality of coils wound on each of the ferrite sections (3223). At this time, it is possible to wind the coils by winding the ferrite once or stacking them twice at equal intervals. Of course, the number of windings is not limited and may be greater than this.
[0136] Additionally, it is effective to connect the coils wound on the ferrite section (3223) in series or parallel according to the aforementioned groups. In this case, when there are three groups, the coil section may have six electrically separated coils protruding. Each of the six coils of the coil section (3224) is connected to one of the six terminals of the generator section, and these terminals may be electrically connected to the first to sixth connection input terminals of the input / output section.
[0137] The housing part (323) is preferably manufactured using various structures and materials to protect the preceding rotating part (321) and fixed part (322) from external impact, with the rotating part (321) and fixed part (322) located inside it. Since the fixed plate part (3221, 3222) of the fixed part (322) is manufactured in a rectangular shape, the housing is also preferably manufactured in a rectangular shape.
[0138] It is effective for the output unit (400) to include an output inverter unit (410) that is connected to the power output unit (312) of the power generation unit (300) and converts and outputs the power generated, and an output display unit (420) that displays the output of the power output unit (312).
[0139] The output inverter unit (410) effectively converts DC power into AC power. This allows the generated power from the power generation unit (300) to be converted into power that can be used externally, making external supply possible. At this time, it is desirable for the output inverter unit (410) to receive DC power and generate a voltage through PWM control. Additionally, it is desirable to remove noise and ripple through a filter circuit so that the signal is output stably. Of course, it is also possible to have a separate control unit to control the switching operation and output voltage in real time.
[0140] It is preferable that the output display unit (420) be positioned between the output inverter unit (410) and the power generation unit (300) to measure and display the output power. Through this, it is possible to check the amount of power output by the power generation unit (300) in real time.
[0141] The feedback unit (500) includes a feedback input unit (510) that receives power, i.e., output power, from the output unit (400), a feedback output unit (520) that provides output power to the starting power generation unit (100), and a feedback control unit (530) that controls the input and output of output power.
[0142] The feedback input section (510) is electrically connected to the output inverter section (410) of the output section (400), and it is effective to receive power from it. The feedback input section (510) can receive DC power from the output inverter section. Through this, DC power can be directly provided to the starting power generation section (100).
[0143] The feedback output unit (520) provides the input power to the starting power generation unit (100) by means of the feedback control unit (530). It is preferable that the feedback output unit (520) be electrically connected to the starting battery unit (120) to provide the output power fed back to the starting battery unit (120), i.e., the feedback power.
[0144] Here, when AC power is provided through the feedback input unit (510), the feedback output unit (520) can convert the AC power into DC and output it.
[0145] The feedback control unit (530) can provide feedback power to the starting power generation unit (100) in accordance with a separate control signal or a request from the starting power control unit (140) of the starting power generation unit (100). Through this, if the power generated by the starting power generation unit (100) itself is insufficient, it may be possible to receive feedback from the output of the power generation unit and utilize it as starting power.
