An Efficient Design for Interleaved Active Clamp Flyback Used in Grid-Connected Solar Microinverter

Abstract

This document presents a high efficient method for interleaved active clamp flyback used in microinverter. The flyback converter was selected as a single stage topology that can boost the low PV panel voltages to a rectified AC output. How to handle the leakage energy for high efficiency and protecting the MOSFET ,how to calculate the parameter and choose the compenent also be showed in this document.
