Abstract

This paper presents a stand-alone fuel cell system for distributed power applications. The adopted system is based on a DC/DC converter and a single-phase three-wire inverter for domestic applications. Full-bridge phase-shift converter with zero voltage switching is used as a front-end stage to convert a fuel cell´s variable DC voltage (low voltage side) into a stable DC voltage (high voltage side). A single-phase three-wire inverter is used to convert the obtained DC voltage into two single-phase 110 V_rms/60 Hz and one 220 V_rms output voltages for household applications. The mathematical model of the adopted system was derived and the control scheme was provided in the paper. The validity and effectiveness of the control scheme was verified by some experimental results.
