Title:
WIRELESS POWER TRANSFER SYSTEM AND WIRELESS POWER RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/149283
Kind Code:
A1
Abstract:
A wireless power transmission device (1) comprises a transmission power supply circuit (11) that outputs sinusoidal power, and a resonant transmission antenna (12) that transmits sinusoidal power. A wireless power reception device (2) comprises a resonant reception antenna (21) that receives sinusoidal power, and a reception power supply circuit (22) that includes a rectifier circuit (24) for rectifying and smoothing sinusoidal power and a waveform control circuit (23) provided between the reception antenna (21) and the rectifier circuit (24). The waveform control circuit (23) passes sinusoidal power and attenuates harmonic components included in non-sinusoidal power generated by the rectifying operation of the rectifier circuit (24).
