ABSTRACT:
When the supply current from a pulse width modulation (PWM) inverter drive circuit supplying current to the motor in an electric-powered motor vehicle is an overcurrent exceeding a particular current level, a monitoring circuit outputs a fail signal to disable the PWM inverter drive circuit and lower the current level. When the current level drops to or below said particular current level, the monitoring circuit re-enables the PWM inverter drive circuit to resume supplying current. If the cumulative output time of the fail signal exceeds a particular period, the PWM inverter drive circuit is determined to not be operating normally, and PWM inverter drive circuit operation is therefore interrupted.
