Abstract
A DC/DC converter has DC input terminals to which a DC power is inputted, a transformer, and a bidirectional switching device on the primary side of the transformer.
Claims6
A DC/DC converter, comprising:
- DC input terminals to which a DC power is inputted;
- a transformer;
- and
- a bidirectional switching unit provided on a primary side of the transformer,
- wherein the bidirectional switching unit includes one or more pairs of bidirectional switching devices and each of the bidirectional switching devices includes two switching elements which are asynchronously turned on and synchronously turned off, and
- wherein an on-timing of one switching element included in one of the bidirectional switching devices is earlier than an on-timing of the other switching element included in said one of the bidirectional switching devices, and the on-timing of said one switching element is synchronized with an off-timing of a switching element included in another of the bidirectional switching devices such that a body diode of the other switching element included in said one of the bidirectional switching devices is turned on to absorb a surge voltage when the switching element included in the another of the bidirectional switching devices is turned off.
