ABSTRACT:
A motor control system for an electric car includes a detector for determining when an input voltage or an output voltage of a DC power circuit falls below a respective predetermined value to operate a switching signal stopper circuit which interrupts or prevents the application of pulse width modulated (PWM) signals to current control elements switching DC currents to generate three-phase AC currents in coils of the motor. The detection of an abnormal drop in the input voltage or the output voltage indicates a malfunction causing excessive currents which could burn out the control elements and/or the power circuit in the absence of prompt interruption of the PWM switching signals.
