Abstract
The present disclosure relates to a power receiver, a resonance-type contactless power supply and a control method. The power converter is coupled between a receiver-side resonant circuit and a load, and is controlled to adjust a current strength parameter of a high-frequency AC current output from the receiver-side resonant circuit, so that a first current strength parameter, which is a peak or an effective value of a current flowing through a transmitting coil, and a second strength parameter, which is a peak or an effective value of a current flowing through a receiving coil, have a predetermined relationship, and a load impendence of an equivalent load is adjusted, and thus system efficiency is optimized.
