“…There are various techniques how to reach ZVS or ZCS depending on the converter topology. The fullbridge dc-dc converter can use active rectifier which ensures the soft-switching (ZCS) of the primary side transistors [2], [4]. Then some kind of a snubber on the secondary side diminishes the switching losses of the secondary side transistors [2]- [4].…”

The paper presents a novel control technique for a phase-shifted PWM (PS-PWM) soft-switching dc-dc converter. The converter is a full bridge dc-dc converter with controlled output rectifier and an active snubber on the secondary side. To solve the problems with nonlinear nature of the dc-dc converter a fuzzy logic control is used. The fuzzy logic controller design and simulation is presented. The performance of the designed fuzzy logic controller is compared to classical PI controller.

“…Few solutions of soft switching DC/DC converter with secondary side active rectifier were already published. The soft switching DC/DC converter with secondary side active rectifier controlled by one switch with secondary side snubber is presented in [1]- [4]. In this kind of converter topology the center tapped full wave controlled rectifier with one transistor switch is used.…”
