Patent Images
1. A wireless power transceiving system comprising:
- a power transmitting apparatus which converts power into a resonance wave and transmits the resonance wave; and
a power receiving apparatus which receives the transmitted resonance wave and converts the resonance wave into direct current (DC) power using a series resonant rectifier circuit which is impedance matched with impedance generated in the power receiving apparatus by parasitic components at a frequency of the resonance wave.
