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.

Abstract: A system of charging a battery of a vehicle is provided. The system includes a charger having a direct current (DC) capacitor to which a DC voltage converted from an AC charge voltage is applied and a first DC converter that converts a magnitude of a voltage of the DC capacitor. A first battery is connected to the first DC converter and is charged with a DC voltage converted by the first DC converter. A second DC converter is connected to the battery and converts a magnitude of a voltage of the battery. A second battery receives a DC voltage converted by the second DC converter. A controller charges the DC capacitor up to a predetermined initial charge voltage using power stored in the second battery by operating the second DC converter and the first DC converter in a backward direction before the AC charge voltage is provided to the charger.

Abstract: A motor driving and battery charging apparatus is provided. The apparatus includes a motor having a plurality of coils, a rectifier circuit connected to the plurality of coils, and a high voltage battery. An inverter generates a driving current from an output voltage of the high voltage battery and supplies the driving current to the motor while the motor operates. While the high voltage battery is charged, the rectifier circuit rectifies an alternating current (AC) of an external power source, the motor and the inverter compensate for a power factor of the current rectified by the rectifier circuit, and the high voltage battery is charged with an output current of the motor and the inverter.
