Mobile wireless power transfer system suppressing reflection by pick-up and reflector

Abstract

A novel Mobile-WPT system is proposed. Impedance matching circuit is separated from resonator and it becomes controllable by variable capacitors. Also, reflection wave back to power source is suppressed by the combination of pick-up and reflector in the receiving unit. Performance fluctuations due to the position shift of vehicle are examined. The performances are not changed so much for both horizontal shift and vertical shift owing to the matching circuit. An experimental system is designed and fabricated. Excellent performance which is well agreed with simulated performance is obtained.
