Abstract
A method and device for controlling a resonant inductor for implementing ZVS in a push-pull parallel resonant inverter is closed. The present disclosure provides A device comprising: a converter including a full-bridge circuit in which a first switch and a second switch form a first leg and a third switch and a fourth switch form a second leg and configured to convert a DC into an AC by turning on or off the switches; a resonant inductor circuit including a resonant inductor and a resonant switch connected in series and connected between two output nodes of the converter; a transmission coil connected in parallel with the resonant inductor circuit; and a controller configured to convert the DC into the AC by providing a switching timing for turning on or off the switches and control a switching timing of the resonant switch based on switching timings of the switches.
