DTC P0A78-272 Drive Motor "A" Inverter Performance: Description

The inverter switches the power transistor on and off based on a driving signal sent from the MG ECU, in order to change the direction of the current that flows into the Generator. The inverter also regulates the duration of the switching time through PWM (Pulse Width Modulation) control, in order to control the voltage applied to the Generator.
