A method for selectively performing a full bridge control and a half bridge control in a WPT system using an LCCL-S resonant network may include: performing the full bridge control by controlling the switches not connected in series of the full bridge inverter to operate simultaneously; calculating a coupling coefficient of the WPT system; determining whether it is possible to switch the full bridge control to the half bridge control based on the calculated coupling coefficient; in response to determining that it is possible to switch the full bridge control to the half bridge control, calculating a load of the WPT system; and performing the half bridge control for the full bridge inverter based on the calculated load.
