[0040] figure 1 It is a schematic diagram of a specific implementation of a high-efficiency power adjustment device based on power factor correction.
[0041] Such as figure 1 As shown, in this embodiment, the high-efficiency power regulation device based on power factor correction of the present invention includes a front-end power factor correction circuit, a back-end power adjustment circuit and a microcontroller.
[0042] The front-end power factor correction circuit includes a full-bridge rectifier circuit TR, an energy storage inductor L, a metal oxide semiconductor field effect transistor (hereinafter referred to as MOSFET) Q, a diode D and an energy storage capacitor C. The sinusoidal voltage Uac obtained from the power grid passes through the full-bridge rectifier circuit TR to output a DC voltage Ui, and then transmits it to the positive terminal of the diode D through the energy storage inductor L, and then outputs it to the positive terminal of the energy storage ...
