DTC P0A79-672 Drive Motor "B" Inverter Performance: Description
WARNING: This page is about a different car, the 2006 Lexus RX 400h. However, it is still accessible from the selected car via links, so may be relevant.
The inverter switches the power transistor on and off based on drive signals received from the MG ECU to change the direction of the current flowing through the Rear Motor. Also, the inverter regulates the duration of the switching time through Pulse Width Modulation (PWM) control, in order to control voltage applied to the Rear Motor.
