Abstract
A resonant power converter includes a full bridge configuration of switching devices and a resonant tank circuit coupled between the full bridge and an isolation transformer having a primary winding and a secondary winding. A full bridge rectifier is coupled between the isolation transformer and a load. A converter controller for generating switching signals for the switching devices includes an outer controller to generate a tank command signal based on a voltage error signal between an output voltage command signal and an actual output voltage signal and an inner controller to generate an actual tank signal based on a secondary winding current and the output voltage command signal. The converter controller also includes a signal generator for generating the switching signals for the switching devices based on a tank error signal between the tank command signal and the actual tank signal.
