Zero-Current-Switching Boost Converter with Coupled Inductors

Abstract

In this study, we propose a zero-current-switching boost converter that uses coupled inductors in order to improve the efficiency for renewable energy generation systems. The coupled inductors for the converter are analyzed by a finite-elements method software. The inductor currents are controlled by a field-programmable gate array (FPGA) and a 2.5MHz analog- to-digital (A/D) converter. The experimental results show that the efficiency of the proposed converter is higher than that of a conventional converter.
