Current-fed DC/DC converter with reverse block IGBT for fuel cell distributing power system

In this paper, the front-end-converter for fuel cell distributing power system is discussed. A current-fed phase shift full bridge (PSFB) ZCS DC/DC converter with reverse block IGBT (RB-IGBT), which is much suitable for fuel cell source, is investigated. Its ZCS operation condition and design consideration have also been discussed. Experimental results of a prototype for a fuel cell distributing power system are given to verify the expected effects.
