BIDIRECTIONAL SWITCHING CONVERTER AND OPERATING METHOD THEREOF

The inventive concepts provide a bidirectional switching converter including a first power metal oxide semiconductor field effect transistor (MOSFET) connecting an input voltage node to a switching node, a second power MOSFET connecting the switching node to a ground node, and a zero current detection (ZCD) auto-calibration circuit configured to perform one of an operation of generating a first offset for varying a turn-on time of the first power MOSFET according to an operation mode and an operation of generating a second offset for varying a turn-on time of the second power MOSFET according to the operation mode.
