Misalignment-Tolerant Series Hybrid with Active Adjustable Constant Current and Constant Voltage Output Wireless Charging System

This paper presents a series hybrid wireless charging system with an active adjustable circuitry offering constant current and voltage output characteristics. The consists of the inductor–capacitor–capacitor (LCC) series-series (SS) networks are used for improving pad misalignment tolerance. An switch is employed to provide CC CV different battery stages. To demonstrate performance proposed method, 310 W prototype was built. A systematic optimization in parameter topology achieve relative analyzed within certain range designed operating region. experimental results indicate that fluctuation less than 5% load variations, varying from 19 70 ?, as pick-up pads misaligned 50% outer diameter.
