Since the input is at high voltage, a capacitor discharge circuit is required to make the board safer to handle after power is disconnected. When power is disconnected, M3 stops pulling the gate to M2 low, allowing current to flow through R3 and bringing the voltage of the caps down from 154V to 60V in about 2 seconds.
