Multi-level resonant push-pull converter for fuel cell system

Abstract

In this paper, the development of high efficiency 1 kW PCS (Power Conditioning System) for utility interactive residential generation by Fuel Cell. Generally the Fuel cell PCS consists of low-voltage DC/DC boost converter part and utility-interactive DC/AC inverter. The high efficiency Multi-level boost-up converter was suggested for high efficiency system. And design and experiment was researched using the grid-interactive inverter.
