Abstract
An electronic system for controlling a power converter having an active clamping circuit includes a current sensor configured to sense current through a primary side of a transformer within the power converter, and a comparator sub-system. The comparator sub-system is configured to receive a transformer current signal from the current sensor and generate a trip signal based on a difference between the transformer current signal and a reference signal. The electronic system also includes a pulse width modulator configured to generate a gate input signal for the active clamping circuit based at least in part on the trip signal.
