Abstract

By the spread of portable electronic devices which need to charge own battery, it have an increased need for contactless power feeding system. To build a convenient desktop feeding system, it is necessary to feed wide area and adapt many kinds of devices. Because of this reason, our group researches a contactless power feeding system using electromagnetic induction on the low coupling between primary and secondary coil. It has only one primary coil, and secondary circuit has resonator made with inductor and capacitor. This resonator can work out wide feeding area and impedance matching for each load.
