Description of the Drawings

[0019] Figure 1 In a preferred embodiment of the present invention, it is a structural schematic diagram of an inverter integrated machine. Detailed Embodiments

[0020] The present invention will be described in detail below with reference to the drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also fall within the scope of the present invention as long as they conform to the gist of the present invention.

[0021] In a preferred embodiment of the present invention, in view of the above problems existing in the prior art, an inverter integrated machine is now provided, as Figure 1 shown, including:

[0022] Control panel 1, the power-taking end SW-IN of the control panel is connected to the starting battery BATTER and the power supply end of the main unit 2 of the inverter integrated machine. The power supply end of the main unit 2 is connected to the power supply VDD, and the power-on signal sending end lock of the control panel 1 is connected to the power-on signal receiving end of the main unit;

[0023] The main unit start button is arranged on the control panel 1.

[0024] Specifically, usually the power supply end SW-IN of the control panel 1 is supplied with electric energy by the power supply VDD, and it will be connected to the control panel 1 only when the main unit is powered on and the power supply VDD is powered. The disadvantage of this circuit connection method is that even when an external battery or external mains input is connected, if the main unit switch W is not turned on, there is no voltage on VDD, and the control panel 1 cannot independently control the power on and off of the main unit.

[0025] In this embodiment, the starting battery BATTTER is set, and the control panel 1 directly takes power from the starting battery BATTER. In this way, only by connecting an external starting battery BATTER, it can be ensured that whether the main unit switch W of the main unit 2 is in the on or off state, there is power supply for the control panel 1. At this time, the panel can send a main unit start signal (LOCK signal) to the main unit to realize the power on and off of the main unit, perfectly solving the defect that the control panel needs to be powered on first to be used.

[0026] In a preferred embodiment of the present utility model, as Figure 1 shown, a first linear voltage regulator circuit 3 is connected between the power-taking end of the control panel 1 and the starting battery BATTER. The first linear voltage regulator circuit 3 includes a first diode D1 and a second diode D2. The anode of the first diode D1 and the anode of the second diode D2 are connected to the starting battery BATTER, and the cathode of the first diode D1 and the cathode of the second diode D2 are connected to the power-taking end SW-IN of the control panel 1.

[0027] In another embodiment, the first linear voltage regulator circuit 3 can also adopt a BUCK chip. The input end of the BUCK chip is connected to the starting battery BATTER, and the output end of the BUCK chip is connected to the power-taking end SW-IN of the control panel 1.

[0028] Specifically, in this embodiment, a linear voltage regulator circuit 3 is set between the control panel 1 and the starting battery BATTER. Because linear voltage regulation is adopted, the power consumption is low. The control panel takes power from the battery end, and the power consumption of the battery is less affected.

[0029] It can be seen that both the diode voltage regulator circuit and the BUCK chip voltage regulator circuit can be adopted. The difference between the two is that the linear voltage regulator circuit composed of diodes ensures less power consumption for the battery compared to the linear voltage regulation and buck circuit using a BUCK chip.

[0030] In a preferred embodiment of the present utility model, as Figure 1 shown, the host 2 includes:

[0031] A host switch W, the second terminal of the host switch W is connected to the power-taking terminal SW-IN of the control panel 1, the first terminal of the host switch W is connected to the anode of the third diode D3, the third terminal is connected to the anode of the fourth diode D4, and the cathodes of the third diode D3 and the fourth diode D4 are connected to one end of the first resistor R1;

[0032] A first triode Q1, the base of the first triode Q1 is connected to the other end of the first resistor R1 and one end of the second resistor R2, and the emitter of the first triode Q2 is connected to the other end of the second resistor R2 and grounded;

[0033] A second triode Q2, the base of the second triode Q2 is connected to one end of the third resistor R3 and one end of the fourth resistor R4, the other end of the third resistor R3 is connected to the emitter of the second triode Q2 and grounded, the other end of the fourth resistor R4 is connected to one end of the first capacitor C1 and one end of the fifth resistor R5, the other end of the first capacitor C1 is grounded, and the other end of the fifth resistor R5 is connected to the host start signal sending end lock of the control panel 1;

[0034] A MOS transistor, the gate of the MOS transistor is connected to one end of the sixth resistor R6 and one end of the seventh resistor R7, the other end of the sixth resistor R6 is connected to the collector of the first triode Q1 and the collector of the second triode Q2, the source of the MOS transistor is connected to the power supply VDD, and the drain of the MOS transistor is connected to the other end of the seventh resistor R7 and the second terminal of the host switch W.

[0035] Specifically, in this embodiment, this part is the circuit in the host that realizes the start function. By pressing the host start button on the control panel, a host start signal (LOCK signal) is sent to one end of the fifth resistor R5 to turn on the MOS transistor so that the host 2 receives the current from the power supply VDD. Subsequently, the conduction state of the host switch W is changed to start the host 2 in different modes. The control panel 1 does not need to be powered on as in the traditional method only when the host switch 2 is turned on;

[0036] The host switch W of the host 2 is a three-terminal double-throw switch. When the switch is thrown to the first terminal and the third terminal, the inverter integrated machine is in different modes, which can be specifically set according to the actual situation. Generally, the first terminal is set to the charging mode, and the third terminal is set to the discharging module.

[0037] In a preferred embodiment of the present utility model, the power supply terminal of the host 1 is also connected to the mains.

[0038] In a preferred embodiment of the present utility model, a second linear voltage regulator circuit 4 is further connected between the power supply terminal of the host 1 and the mains power supply.

[0039] Specifically, as Figure 1 shown, in this embodiment, after the host 2 is powered on on the control panel 1, the external mains power supply can also be input through the power interface S1 and then rectified and stepped down, and a linear voltage regulator circuit 4 composed of diodes is also provided. The inverter integrated machine can charge the starting battery BATTER in the charging mode, which can solve the problem of battery power consumption.

[0040] The above is only a preferred embodiment of the present utility model, and does not limit the implementation manners and protection scope of the present utility model accordingly. For those skilled in the art, it should be able to realize that all the solutions obtained by equivalent substitution and obvious changes made by using the content of this specification and the drawings should be included in the protection scope of the present utility model.
