摘要：

In this paper, an averaged model for a recently proposed novel three-phase transformer-isolated phase-shift DC/DC converter is derived. Fuel cell static and dynamic characteristics are used for the converter power stage design consideration. The controller is then designed based upon the power stage parameters and system dynamic requirements. The entire system has been designed, simulated, and verified with a 3-kW converter prototype and a commercial 1.2 kW fuel cell. The experimental results match the simulation results very well on both fuel cell source dynamic and step load transient responses.
