ABSTRACT:
A primary regulator having a zero-crossing detector and a voltage reference coupled to a processor is provided. The processor controls the on time of a primary transformer via a switching device isolated from the processor via a coupler A method of regulating a power supply to maintain a desired output voltage at a load including the steps of measuring an average output voltage at a load and controlling the on time of a switching device serially connected to a primary transformer input based on the measured output voltage and a zero-crossing signal.
