High Step-Up Dc-Dc Converter For Fuel Cell Powered Residential Power Generation System

This paper presents a new high voltage boosting DC-DC converter topology intended for residential fuel cell power systems. The proposed system consists of a high voltage boosting dc–dc converter to boost the fuel cell voltage to 350 V dc and a pulse-width modulated inverter with filter to convert the dc voltage to 240V ac. The operating principle of the dc-dc converter is based on bootstrap capacitors or charge pumps and series boost inductors. Furthermore, although three switches are used, no isolated gate driver is needed instead one half-bridge gate driver and one low-side gate driver is used. Accordingly, the proposed converter is easy in analysis and simple in implementation. Simulation and experimental results are demonstrated.
