Abstract

This paper investigates the effect of snubber capacitor on the zero voltage switching (ZVS) boundary of the dual active bridge (DAB) DC-DC converter. The analysis is performed to determine the minimum current required during transistor turn-off to achieve successful ZVS and the ZVS boundary operating conditions of the converter are obtained. The operation of the converter during transistor turn-off with snubber capacitor is explained. SABER simulations verify the operation of the converter under ZVS thereby confirming the accuracy of the analysis. Experimental results corresponding to the ZVS boundary of the converter prototype for 6.4kW, 390V/175V, 20 kHz operation are included to support the analysis.
