Title:
POWER RECEPTION DEVICE, POWER TRANSMISSION SYSTEM, PROGRAM, AND POWER RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/160978
Kind Code:
A1
Abstract:
The impedance of a rectifying section (1060) is variable. A measurement point (P) of a power measuring section (1080) is between a power receiving section (1020) and the rectifying section (1060). The power receiving section (1020) receives AC power (AC) transmitted wirelessly from a power transmission device (2000) and outputs the same to a matching section (1040). The matching section (1040) matches the output impedance of the power receiving section (1020) and the input impedance of the rectifying section (1060). The rectifying section (1060) accepts AC power (AC) from the matching section (1040) and converts the same to DC power. The power measuring section (1080) measures the power value (W) of the AC power (AC) at the measurement point (P). A control section (1100) controls the impedance of the rectifying section (1060) by changing, on the basis of the power value (W), the value of voltage applied to the rectifying section (1060).
