摘要： The present invention relates to a converter and a driving method thereof. The converter includes a switch controller that controls switching operation of a master switch and a slave switch. The switch controller detects a center point of one switching operation period of the master switch by using an internal triangular wave having a period that is the same as that of the one switching operation period, and starts the switching operation of the slave switch at the detected point. The internal triangular wave signal has a waveform that varies within one period, and detects a crossing point of an average value of the internal triangular wave and the internal triangular wave as a center point of one switching operation period of the master switch.
