연료전지용 Simulator에 의한 PWM 컨버터/인버터 구동시스템에 관한 연구

A Study on PWM Converter and Inverter Drive System by a Fuel Cell Simulator

Fuel cell is remarkable for one of the clean energy recently. But in the fuel cell case, it has characteristics with low voltage and high current. Therefore, for using domestic power, it should be changed to the power source with commercial voltage and frequency. In this paper fuel cell simulator having electrical characteristics is designed and constructed instead of fuel cell stack. Voltage generated from fuel cell is from 39V to 72V dc and should be boosted to 400v do for home appliances. A stand alone system including the inverter and DC/DC converter for the fuel cell is then proposed. Experimental result is used to support the analysis.
