Maintenance principles of APW12 1215b PSU PFC circuit

The PFC circuit will boost the 300V DC voltage output by the bridge rectifier to 400V. There are 2 PFC circuits on the APW12 1215b power supply, and their components and working principles are the same. Both circuits will include PFC inductors, PFC MOS tubes, PFC diodes and two 450V capacitors. Studying this training video can help you master how to quickly troubleshoot 1215b PFC circuits.
