A Load-Independent Output Voltage Operation of a Multi-Receiver WPT System

Multi-receiver of wireless power transfer (WPT) systems benefit from reducing the device of the power supply. However, the variation of the magnetic coupling coefficient and the load resistance of each receiver was considered because it usually affects the operating point and the output for each receiver. This paper presents the design approach of a load- independent output voltage operation for a multi-receiver. Simulation results have shown that the proposed design method can provide constant output voltage even load resistance of each receiver is different.
