Abstract
A power conversion device includes a step-down-type transformer and a bridge circuit that rectifies output voltage of the transformer and supplies the rectified output voltage to a load. The bridge circuit is connected to a secondary winding of the transformer and includes MOS-FETs connected in series and diodes connected in series. A gate of the MOS-FET is connected to one end of a primary winding of the transformer with a capacitor interposed therebetween and a gate of the MOS-FET is connected to the other end of the primary winding of the transformer with a capacitor interposed therebetween. With this, a power conversion device and a wireless power transmission system that can achieve space saving and reduce loss in a rectifying element are provided.
