Abstract

This application note provides detailed guidance on leveraging the configurable logic block (CLB) module of the real-time C2000™ MCU. Leveraging this CLB module creates robust and simple synchronous rectification (SR) pulse width modulation (PWM) signals for the desired SR control of LLC resonant converters. The proposed method implements SR control without any software effort during runtime.

This application note provides insight with realistic examples showcasing how to interact with CLB and EPWM modules.
