Abstract

This paper presents the analysis and design procedures of a new DC-DC full bridge PWM converter using the ZVS-PWM commutation cell to achieve soft switching. Experimental results obtained from a laboratory prototype rated 1500 W are also presented. It is demonstrated that the inclusion of the auxiliary switches do not modify the PWM switching pattern. Bench tests on the prototype confirm that the proposed circuit exhibits high efficiency and behaves as a constant voltage source over an extended power output range
