Patent 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.
