Abstract: A current controller for an electric machine that includes an input, an output, a threshold generator and a comparator. The threshold generator stores a scaling factor and includes a PWM module that operates on a reference voltage to generate a threshold voltage. The duty cycle of the PWM module is then defined by the scaling factor. The comparator compares a voltage at the input against the threshold voltage and causes an overcurrent signal to be generated at the output when the voltage at the input exceeds the threshold voltage.

Abstract: A control system for an electric machine, the control system including a current controller and a drive controller. The current controller includes an input, an output, a comparator and a latch. The comparator sets the latch when a voltage at the input exceeds a threshold, and the latch outputs an overcurrent signal when set. The drive controller then resets the latch after a predetermined period of time.
