Abstract
Provided is a system of varying a dead time of a converter, including a converter including a plurality of semiconductor switches to which a dead time is applied during an alternate switching operation; and a controller controlling ON/OFF of the plurality of semiconductor switches and setting the dead time, wherein the controller varies the dead time during an operation of the converter. According to the present invention, an over dead-time may be detected and varied to an appropriate dead time, thereby minimizing power loss of the converter and increasing efficiency thereof.
