Abstract
A method for performing switching synchronization of a bridgeless rectifier in an electric vehicle (EV) wireless power transfer system may include receiving, by an EV control module, an input voltage of a transmission-side resonance circuit from a transmission-side of the EV wireless power transfer system; calculating, by the EV control module, a phase difference between the received input voltage and a voltage or a current selected in the bridgeless rectifier and a reception-side resonance circuit; and controlling, by an EV control module, switching time points of switches included in the bridgeless rectifier to decrease the calculated phase difference. The reception-side resonance circuit may be electromagnetically coupled to the transmission-side resonance circuit, and the bridgeless rectifier may be configured to rectify an output of the reception-side resonance circuit and to output the rectified output.
