采用交错开关的双接收线圈无线电能传输系统

This letter presents a wireless power transfer (WPT) system for wristband device charging. By using dual receiver coils with power switches in an interleaved manner, the proposed WPT system can simultaneously operate to accumulate energy from the primary coil and transfer the previously accumulated energy to the battery in each coil. As a result, the WPT efficiency can be increased with the small ...
