Abstract: Wireless energy transfer is of high interest, and applications such as RFID, implantable devices, electric vehicles, and charging cell phones are widely used. Power dissipation of power MOSFETs used in these applications affect efficiency of such circuits. In this paper a special method has been used to lower energy dissipation of inverters and replace MOSFETs with energy storing elements in the circuit. In the new method two MOSFETs have been omitted from the inverter bridge circuit. A self-oscillating full-bridge MOSFET-inductor circuit with high efficiency and low power dissipation has been implemented with minimum component. The implemented circuit has 24% efficiency at 20cm distance for energy transfer.
