Reconfigurable Receiver With Adaptive Output Voltage for Wireless Power Transfer

Omnidirectional wireless power transfer (WPT) can simultaneously power multiple loads. The power or voltage needed by various loads inevitably differ at diverse stages. It is difficult or impossible to meet the power requirements of all loads only by the adjustment of transmission power. A reconfigurable receiver that can actively adjust the receiving power is proposed in this paper. The reconfigurable receiving coil is divided into multiple segments. The mutual inductance of coupler is adjusted adaptively by the number of segments selected for power receiving to ensure that the voltage and power are stable within a certain range, or meet the various requirements of different loads and stages. Simulations and experiments were carried out. The adaptive adjustment of reconfigurable receiver on the output voltage and power is verified. It provides a new idea for the output regulation of WPT.
