The schematic top clearly separates from N (power ground) . They are usually connected at a single point (star ground) on the PCB, but shorting them randomly invites noise into the gate drive circuits. Mounted to the secondary heatsink to smooth out
, the PCB is segmented into distinct primary (high voltage) and secondary (low voltage) zones. A clear white "isolation line" or silkscreen dividing line runs down the center of the board. 1. Input Filtering & Surge Protection (AC Inlet Section) They are usually connected at a single point
Although sometimes external to the module, the top schematic typically includes:
