Description
Summary:This paper presents the analysis of the mechanism of failure modes in bi-directional phase-shift full-bridge converters, composed of MOSFET, based on the circuit operation and parameters considering parasitic components of MOSFET. In addition, the relation between circuit operation and parameters are suggested through the experimental comparison. Using the relation, the suitable ranges of parameters for the stable performance are analyzed. The design criteria of the bi-directional phase-shift full-bridge converter are presented and evaluated by the experimental verification.
