Design and Optimization of a Resonant Converter for Wireless Power Transfer

Inhalt:
Electrified Transportation needs a source of electrical energy. One of possible power sources is a rechargeable battery. The vehicle’s on-board battery is charged via power cable connected or by implementation of Wireless Power Transfer (WPT) technology. Basic WPT technology is strongly-coupled magnetic resonance. The resonance frequency and power transmitted is depending on the relative position of the transmitting and receiving windings. In this paper we consider resonance power converter for resonant WPT. Issues on power transmitted and resonant frequencies variations depending on the relative position of the transmitting and receiving coils are considered.
