Abstract
This paper deals with the ZVS characteristics of a bidirectional DC/DC converter in idling mode. Simulations are carried out with the supercapacitor which maximum voltage is 50 V. It is found that the ZVS can be achieved as far as the supercapacitor voltage is below 94% of the maximum voltage in idling mode. Therefore, the switching loss in the mode can be small by control the upper limit of the supercapacitor voltage.
