Antminer APW9 plus power supply EMI filter circuit

The APW9+ power supply has 2 EMI circuits, which is different from the APW3+. These 2-way EMI circuits are composed of X capacitors, Y capacitors, and common mode inductors, and their functions are to filter the 220V AC input power. Therefore, this lesson will explain the structural design and measurement of the EMI circuit in the AW9+ PSU.
