Abstract

This paper presents the implementation of 1 kW prototype high frequency link boost half bridge inverter-fed DC-DC power converter with bridge voltage-doublers suitable for small scale PEM fuel cell system and its associated control scheme. The operation principle of this converter is described using fuel cell modeling and some operating waveforms and the switching mode equivalent circuits based on simulation results and a detailed circuit operation analysis and soft-switching conditions.
