Principle and measurement for APW12 1215b EMI filter circuit

Principle and measurement for APW12 1215b EMI filter circuit The power supply APW12 1215b sui for Antminer S19j S19a has 2 EMI circuits. When 220V AC voltage is input, interference will be filtered out in these two circuits first, and then 300V DC voltage will be output after rectification by the subsequent bridge stack. The components of both circuits are the same and, of course, the circuit connections are the same. If it is damaged, the output voltage will not meet the working requirements of the power supply.
