ABSTRACT:
A controller for a power inverter having a gate assembly with an alternating current power output. A gate driver controls the activation of the gate assembly while a processor controls the operation of the gate driver. A current sensor has an output signal representative of the current at the power output. A noise detector circuit provides an output signal to the processor of the frequency of electromagnetic noise in the power inverter and the processor is programmed to sample the current from the current sensor at the frequency of the noise.
