Abstract

The battery is mostly adopted as the load in current wireless charge applications. The wireless charger should provide configurable constant current (CC) and constant voltage (CV) outputs for the batteries. The implementation of configurable CC and CV outputs mostly rely on the additional dc–dc converter, hybrid topology, or high-order networks, resulting in complex control and poor reliability. Moreover, the battery wireless charger should also have anti-misalignment ability. To attack the above problems, a hybrid battery wireless charger is proposed for self-adapting battery charging curve and antimisalignment. A double-solenoid quadrature coupler (DSQC) consisting of square quadrature coil and double-solenoid coil is designed, which combines the coupler with clamp circuit to switch between the two coils automatically, ensuring that the output voltage has small fluctuation within a large lateral misalignment range and inherent CC-to-CV output. The control means is relatively simple, the output threshold is not limited by the parameters of DSQC. Eventually, an experimental prototype with 100 V/4.1A output is built to verify the correctness of the proposed scheme.
