Abstract

This application note describes the implementation of a Full-Bridge LLC resonant converter based on the UCC25661x LLC controller. Since the controller is primarily intended for Half-Bridge applications, additional circuitry is employed to generate the required gate-drive signals and necessary features for Full-Bridge operation.
