Inverter Main Power Board (Mainboard)
The mainboard contains the DC-DC boost and DC-AC conversion stages where the DC Bus voltage is regulated. A failure in the PWM (Pulse Width Modulation) control loop or a shorted MOSFET/IGBT prevents the system from clamping the bus voltage within safe operational parameters. Replacing the mainboard restores the integrated sensing and switching logic necessary to maintain bus stability.
