Current-fed phase shift controlled full bridge ZCS DC-DC converter with reverse block IGBT

Abstract

This paper investigated a current-fed phase shift full bridge (PSFB) ZCS DC/DC converter with reverse block IGBT (RB-IGBT), which is much more suitable to IGBT devices. Its ZCS operation condition is also been discussed. Experimental results of a 4 kW prototype are given to verify the expected effects.
