    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.

  • Patent number: 8699649
    Abstract: A clock and data recovery circuit is disclosed. The clock and data recovery circuit in accordance with an embodiment of the present invention uses a hybrid phase detector that is constituted by including a linear phase detector and a binary phase detector. Since the clock and data recovery circuit basically is constituted with the linear phase detector, a charge pump, a loop filter, a voltage controlled oscillator and a D flip flop to recover clock and data, a phase detector gain is irrelevant to the jitter of received data and recovered clock, and it is possible to make a fine adjustment of the size of up/down currents of the charge pump using the binary phase detector and a charge pump controller, thereby compensating a phase offset between the received data and the recovered clock.
