Antminer APW3 plus power supply PFC circuit

The PFC circuit is an important part of the Antminer APW3+ power supply, so this lesson will explain in detail the working principle of the PFC circuit in the APW3 plus PSU. Including the components of the PFC circuit (such as PFC chip, inductor, MOS tube, diode and two 450V capacitors), the role of PFC circuit in the whole power supply, how to detect the direction of the circuit, and the circuit connection of the MOS tube in the PFC circuit.
