[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , an AI-controlled energy-saving power supply circuit, comprising:

[0036] A mains power supply module, used to introduce the mains voltage as a second power supply and output it to the voltage stabilizing output module;

[0037] A solar power supply module is used to convert solar energy into electrical energy as a first power supply and output it to a voltage-stabilizing output module;

[0038] The voltage-stabilized output module is used to convert the power input into a stable voltage output;

[0039] The first output end of the mains power supply module is connected to the input end of the voltage stabilizing output module and the first output end of the solar power supply module, the second output end of the mains power supply module is connected to the input end of the solar power supply module, and the second output end of the solar power supply module is connected to the input end of the mains power supply module.

[0040] In this example: See Figure 2 , the mains power supply module includes:

[0041] The AC / DC conversion submodule is used to convert the mains power into DC power through voltage reduction, rectification and filtering, and supplies the DC power to the voltage stabilization output module as the second power supply;

[0042] The light intensity collection and output submodule is used to collect the ambient light intensity. When the ambient light intensity is lower than a first threshold, the solar power supply module is not driven to work, and when the ambient light intensity is higher than the threshold, the solar power supply module is driven to work;

[0043] The first output end of the AC / DC conversion submodule is connected to the input end of the voltage stabilization output module, the second output end of the AC / DC conversion submodule is connected to the input end of the light intensity collection output submodule, and the output end of the light intensity collection output submodule is connected to the input end of the solar power supply module.

[0044] In this example: See Figure 2 The AC / DC conversion submodule includes a transformer W, a rectifier T, a first capacitor C1, a second capacitor C2, a first inductor L1, a first MOS tube V1, and a first diode D1. The input end of the transformer W introduces the mains electricity, one end of the output end of the transformer W is connected to the first end of the rectifier T, the other end of the output end of the transformer W is connected to the third end of the rectifier T, the second end of the rectifier T is grounded, the fourth end of the rectifier T is connected to one end of the first inductor L1 and one end of the first capacitor C1, the other end of the first capacitor C1 is grounded, the other end of the first inductor L1 is connected to one end of the second capacitor C2, the S pole of the first MOS tube V1, and the input end of the light intensity collection output submodule, the other end of the second capacitor C2 is grounded, the G pole of the first MOS tube V1 is connected to the second output end of the solar power supply module, the D pole of the first MOS tube V1 is connected to the positive pole of the first diode D1, and the negative pole of the first diode D1 is connected to the input end of the voltage stabilization output module.

[0045] After the mains power is introduced, it is stepped down by the transformer W, converted into AC / DC by the rectifier T, and filtered by the filter circuit composed of the first capacitor C1, the second capacitor C2, and the first inductor L1. Finally, when the first MOS tube V1 is turned on, the voltage passes through the first MOS tube V1 and the first diode D1 to supply power to the voltage stabilizing output module.

[0046] In another embodiment, the rectifier T may be replaced by a bridge rectifier circuit.

[0047] In this example: See Figure 2 The light intensity collection and output submodule includes a first potentiometer RP1, a third resistor R3, a third capacitor C3, a photoresistor RG, a fourth amplifier U4, and a fourth resistor R4. One end of the first potentiometer RP1 is connected to the second output end of the AC / DC conversion submodule, the other end of the first potentiometer RP1 is connected to one end of the third resistor R3, the other end of the third resistor R3 is connected to one end of the third capacitor C3, one end of the photoresistor RG, and the inverting end of the fourth amplifier U4, the other end of the third capacitor C3 is grounded, the other end of the photoresistor RG is grounded, the in-phase end of the fourth amplifier U4 is connected to the first reference voltage VREF1, the output end of the fourth amplifier U4 is connected to one end of the fourth resistor R4, and the other end of the fourth resistor R4 is connected to the input end of the solar power supply module.

[0048] When the environment is bright, the voltage on the photoresistor RG is too small, the reference voltage at the in-phase terminal of the fourth amplifier U4 is higher than the inverting terminal voltage, and the fourth amplifier U4 outputs a high level to drive the solar power supply module to work. When the environment is dim, the voltage on the photoresistor RG is too large, the in-phase terminal voltage of the fourth amplifier U4 is lower than the inverting terminal voltage, and the solar power supply module is not driven to work.

[0049] In another embodiment, the first reference voltage VREF1 can be obtained through devices such as a voltage stabilizer and a voltage regulator tube.

[0050] In this example: See Figure 3 , the solar power supply module includes:

[0051] A voltage processing submodule, used for converting solar energy into direct current as a first power supply to supply the voltage stabilizing output module;

[0052] A voltage acquisition submodule is used to collect the voltage of the first power supply, obtain a sampled voltage, and when the sampled voltage is lower than a second threshold, construct a power supply circuit for the mains power supply module and the voltage stabilizing output module; when the sampled voltage is higher than the second threshold, disconnect the power supply circuit for the mains power supply module and the voltage stabilizing output module;

[0053] The input end of the voltage processing submodule is connected to the second output end of the AC power supply module, the first output end of the voltage processing submodule is connected to the input end of the voltage stabilizing output module, the second output end of the voltage processing submodule is connected to the input end of the voltage collection submodule, and the output end of the voltage collection submodule is connected to the input end of the AC power supply module.

[0054] In this example: See Figure 3 The voltage processing submodule includes a solar panel X, a fifth resistor R5, a second MOS tube V2, a third diode D3, a fourth capacitor C4, and a second diode D2. One end of the solar panel X is grounded, and the other end of the solar panel X is connected to one end of the fifth resistor R5. The other end of the fifth resistor R5 is connected to the D pole of the second MOS tube V2, the G pole of the second MOS tube V2 is connected to the second output end of the mains power supply module, the S pole of the second MOS tube V2 is connected to the positive pole of the third diode D3, the negative pole of the third diode D3 is connected to one end of the fourth capacitor C4, the positive pole of the second diode D2, and the input end of the voltage collection submodule. The other end of the fourth capacitor C4 is grounded, and the negative pole of the second diode D2 is connected to the input end of the voltage stabilization output module.

[0055] The solar panel X converts solar energy into electrical energy, which is then output to the voltage-stabilizing power supply module after passing through the second MOS tube V2, the third diode D3, the fourth capacitor C4, and the second diode D2. When the environment is bright, the second MOS tube V2 is turned on, and when the environment is dark, the second MOS tube V2 is turned off.

[0056] In another embodiment, a light emitting diode may be provided to indicate the working status.

[0057] In this example: See Figure 3 The voltage acquisition submodule includes a second resistor R2 and a first resistor R1. One end of the second resistor R2 is connected to the second output end of the voltage processing submodule, the other end of the second resistor R2 is connected to one end of the first resistor R1 and the second input end of the AC power supply module, and the other end of the first resistor R1 is grounded.

[0058] The first resistor R1 samples the output voltage of the voltage processing submodule. When the power supply is insufficient, the voltage on the first resistor R1 is insufficient to drive the first MOS tube V1 to be cut off. On the contrary, when the power supply is sufficient, the voltage on the first resistor R1 is large enough to drive the first MOS tube V1 to be cut off.

[0059] In another embodiment, a voltage stabilizing diode may be added to avoid erroneously triggering the first MOS tube V1 to turn on or off.

[0060] In this example: See Figure 4 , the voltage regulated output module includes:

[0061] A voltage output submodule, used for outputting direct current to supply electrical loads;

[0062] The feedback regulation submodule is used to sample the DC power output by the voltage output submodule and obtain the feedback voltage to adjust the DC power output of the voltage output submodule and build a regulated voltage output;

[0063] The first input end of the voltage output submodule is connected to the first output end of the AC power supply module and the first output end of the solar power supply module, the output end of the voltage output submodule is connected to the input end of the feedback regulation submodule, and the output end of the feedback regulation submodule is connected to the second input end of the voltage output submodule.

[0064] In this example: See Figure 4 The voltage output submodule includes a sixth resistor R6, a third MOS tube V3, and a fourth MOS tube V4. The D pole of the third MOS tube V3 is connected to one end of the sixth resistor R6, the first output end of the AC power supply module, and the first output end of the solar power supply module. The other end of the sixth resistor R6 is connected to the G pole of the third MOS tube V3 and the D pole of the fourth MOS tube V4. The S pole of the fourth MOS tube V4 is grounded. The G pole of the fourth MOS tube V4 is connected to the output end of the feedback regulation submodule, and the S pole of the third MOS tube V3 is connected to the input end of the feedback regulation submodule.

[0065] After the voltage is input, the third MOS tube V3 is triggered to be turned on through the sixth resistor R6, and the voltage is output to the power load through the third MOS tube V3.

[0066] In another embodiment, other types of switch tubes may be used to replace the third MOS tube V3.

[0067] In this example: See Figure 4 The feedback regulation submodule includes a seventh resistor R7, an eighth resistor R8, a first amplifier U1, a second inverter U2, a third inverter U3, a ninth resistor R9, and a fifth capacitor C5. One end of the seventh resistor R7 is connected to the output end of the voltage output submodule, the other end of the seventh resistor R7 is connected to one end of the eighth resistor R8, the in-phase end of the first amplifier U1, and the power supply end of the first amplifier U1, the other end of the eighth resistor R8 is grounded, the inverting end of the first amplifier U1 is connected to the second reference voltage, the output end of the first amplifier U1 is connected to the power supply end of the second inverter U2, the input end of the second inverter U2 is connected to one end of the fifth capacitor C5 and one end of the ninth resistor R9, the other end of the fifth capacitor C5 is grounded, the output end of the second inverter U2 is connected to the other end of the ninth resistor R9 and the input end of the third inverter U3, and the output end of the third inverter U3 is connected to the second input end of the voltage output submodule.

[0068] When the output voltage VOUT increases, the voltage on the eighth resistor R8 increases, the voltage at the in-phase terminal of the first amplifier U1 increases, the voltage at the power supply terminal of the first amplifier U1 increases, the output voltage of the first amplifier U1 increases, and the power supply voltage of the second inverter U2 increases, so that the charging speed of the fifth capacitor C5 increases, the discharging speed remains unchanged, the duty cycle of the formed square wave signal decreases, the duty cycle of the square wave signal (PWM) formed after the third inverter U3 increases, the conduction frequency of the fourth MOS tube V4 increases, the conduction frequency of the fourth MOS tube V4 decreases, and the output voltage VOUT decreases; conversely, when the output voltage VOUT decreases, the duty cycle of the square wave signal (PWM) output by the third inverter U3 decreases, and the output voltage VOUT increases, thereby constructing a regulated output.

[0069] In another embodiment: other devices such as 555 chip can be used to construct square wave signal output.

[0070] The working principle of the present invention is: the AC power supply module is used to introduce the AC voltage, which is used as the second power supply and output to the voltage-stabilizing output module; the solar power supply module is used to convert solar energy into electrical energy, which is used as the first power supply and output to the voltage-stabilizing output module; the voltage-stabilizing output module is used to convert the power supply input into a stable voltage output.

[0071] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0072] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
