Whatsminer P222C power supply PFC circuit

After the voltage comes out of the EMI circuit, it will enter the very important PFC circuit part. The 220V voltage will be rectified in this circuit, and after the superposition of two voltages, a 420V voltage will be output to power the switching MOS tubes in the main power area, the transformer and the thick film chip in the No. 1 auxiliary power area. Only when the PFC circuit works normally, the voltage will continue to supply the subsequent circuit.
