Purpose

Author: Justin O'Shea, Microchip Technology Inc.

The purpose of this application note is to provide a solution for implementing a dual 3-phase interleaved half-bridge LLC resonant converter with the resources provided by the dsPIC33AK device family. The document provides an overview of the circuit topology, control scheme and implementation details of the PWM initialization and control firmware. The scope is limited to the setup of the PWM and its basic operation.
