Abstract
This paper presents the analysis and design procedures of a new dc-dc full bridge pulsewidth modulation (PWM) converter, using the zero voltage switch (ZVS)-PWM commutation cell to achieve soft switching. Experimental results obtained from a laboratory prototype rated 1500 W are also presented. It i s demonstrated that the inclusion of the auxiliary switches does not modify the PWM switching pattern. Bench tests on the prototype confirm that the p roposed circuit exhibits high efficiency and behaves as a constant voltage source over an extended power output range.
