  • Contactless power reception circuit and contactless power transmission system
    Patent number: 8674552
    Abstract: This disclosure provides a contactless power reception circuit that includes a power reception part, a voltage rectifying part, a voltage transforming part and a load modulation part. The voltage transforming part includes a smoothing capacitor, a DCDC converter and a backflow prevention device. The power reception part is couplable with an electromagnetic field adjacent to the contactless power reception circuit. The rectifying part rectifies a voltage output from the power reception part, the voltage transforming part transforms rectified voltage from the rectifying part, and the load modulation circuit conducts a load modulation while signals are transmitted. The smoothing capacitor smoothes a voltage input to the voltage transforming part, the DCDC converter transforms voltage smoothed by the smoothing capacitor, and the backflow prevention device prevents backflow of charge from the smoothing capacitor while the signals are transmitted to a contactless power transmission circuit.
