Antminer APW12 1215b PSU structure and powering

There are many versions of Antminer APW12 power supplies. There will be slight differences in circuit connections between different versions. ZMRC is now launching a maintenance course for the 1215b version of this PSU. The AC input 220V will first enter the EMI circuit for filtering, then pass through the PFC circuit and auxiliary power area in sequence, and then supply power to the main power chip. Only when everything is normal will the 15V DC voltage be output. In this lesson, we will first understand the structural layout of each part of the APW12 1215b power supply, as well as the detailed circuit connections.
