Control of Power Distribution for Multiple Receivers in SIMO Wireless Power Transfer System

Control of Power Distribution for Multiple Receivers in SIMO Wireless Power Transfer System

A method to control the power distribution among receivers by the load values in a single-input, multiple-output (SIMO) wireless power transfer (WPT) system is investigated. We first derive the value of loads to maximize total efficiency. Next, a simple, but effective analytical formula of the load...
