The microcontroller controls the inverter to perform electric energy self-adaptive regulation work according to the detected working voltage parameters and working current parameters of the power equipment. However, when an abnormal MOS tube appears in the inverter, the inverter will stop working, and the power supply control to the power equipment cannot be continued. In addition, due to the limited output power range and low voltage gain of the inverter, the power demand of high-power power equipment cannot be met, and thus there is room for improvement. SUMMARY

[0055] In this embodiment, a power equipment adaptive regulation control circuit receives DC power from the power port. A first capacitor C1 filters the power. The IO2, IO4, IO1, and IO3 terminals of the first controller U1 drive the conduction states of the third power transistor Q3, the fourth power transistor Q4, the fifth power transistor Q5, and the sixth power transistor Q6, respectively. This, in conjunction with the third inductor L3, the first capacitor C1, and the first transformer B1, performs inversion processing. After the first transformer processes the power, the output port supplies power to the connected power equipment. When higher output power is required, the IO5 terminal of the first controller U1 drives the second power transistor Q2, the first thyristor S1, and the third thyristor S3 to conduct. The first inductor L1 and the second inductor L2 store... The electrical energy released by the energy storage device is regulated by the second power transistor Q2 so that the first controller U1 can compensate for the output electrical energy of the inverter when driving the inverter output module 6 to perform positive and negative cycle inversion, thereby increasing the output power. The third inductor L3 and the third capacitor C3 then filter the output, and the first transformer B1 adjusts the output.

Resistor R1, first inverter INV1, and first logic unit J1 determine whether the third power transistor Q3 is conducting; second resistor R2, second inverter INV2, and third logic unit J3 determine whether the sixth power transistor Q6 is conducting. Similarly, when the first controller U1 drives the fourth power transistor Q4 and the fifth power transistor Q5 to conduct, the first detection device determines whether the fourth power transistor Q4 is conducting, and the second resistor R2, second inverter INV2, and second logic unit J2 determine whether the fifth power transistor Q5 is conducting. When the third power transistor Q3 is not conducting, the IO9 terminal of the first controller U1 controls the first power transistor Q1 and the first thyristor S1 to conduct, so that the electrical energy released by the energy storage device passes sequentially through the first diode D1, the first power transistor Q1, and the second diode D... 2. When the first power transistor Q2 is not turned on, the first controller U1's IO8 terminal will control the first power transistor Q1 and the third power transistor S3 to turn on, replacing the fourth power transistor Q4. When the sixth power transistor Q6 is not turned on, the first controller U1's IO7 terminal will turn on the second power transistor Q2 and the fourth power transistor S4, so that the electrical energy transmitted from the second end of the primary side of the first transformer B1 is transmitted through the fourth power transistor S4 and the second power transistor Q2, replacing the sixth power transistor Q6. Similarly, when the fifth power transistor Q5 is not turned on, the first controller U1's IO6 terminal will control the second power transistor Q2 and the second power transistor S2 to turn on, replacing the fifth power transistor Q5.If the third power transistor Q3 and the sixth power transistor Q6 are both off, or if the fourth power transistor Q4 and the fifth power transistor Q5 are both off, the inverter operation will stop.
