Abstract
A bidirectional DC-DC converter is disclosed. According to the bidirectional DC-DC converter, switching loss is reduced by implementing zero voltage switching of switching devices in a boost mode of the bidirectional DC-DC converter. Accordingly, it is possible to realize the high efficiency of power conversion. Further, switching devices of the bidirectional DC-DC converter are controlled using simple logic devices, thereby controlling a plurality of directional DC-DC converters coupled in parallel to each other.
