Transmitter Module Optimization for Wireless Power Transfer Systems with Single Transmitter to Multiple Receivers

Most of the coil designs for wireless power transfer (WPT) systems have been developed based on the “single transmitter to a single receiver (S-S)” WPT systems by the empirical design approaches, partial domain searches, and shape optimization methods. Recently, the layout optimizations of the recei...
