Abstract
A novel magnetic coupled charger is proposed, that is suitable for small electric devices. In this charger, standby power is reduced for energy saving. Eddy current heating in metal placed near it, is reduced by using a feedback transformer. In this circuit, a power factor correction is also realized to be 99%
