Abstract

This paper studies construction and control of the proton exchange membrane fuel cell (PEMFC) power system. A high efficiency topology without electrolytic capacitor is proposed for both grid-connected mode and stand-alone mode. A voltage balance control strategy for front-end DC/DC converter is presented. A Power management unit (PMU) is introduced to provide the transient power on step load and absorb low-frequency ripple under the condition of unbalance load. It improves the dynamic response of the system and replaces the bulky DC-Bus capacitors. A seamless modes transfer strategy is introduced. A 30kW FC power system with its control is verified by experimental results.
