SYSTEM AND METHOD FOR REACTIVE POWER CONTROL IN DYNAMIC INDUCTIVE POWER TRANSFER SYSTEMS

摘要

Systems and methods for dynamically tuning reactive power in an inductive power transfer system are disclosed. The system comprises a first plurality of coils operably coupled to a respective ferromagnetic material, configured to receive wireless power via the ferromagnetic material from a power source. The system further comprises a plurality of switches configured to selectively control power received by certain of the first plurality of coils. The system further comprises a second plurality of coils configured to receive current from respective ones of the first plurality of coils and deliver wireless power to a wireless power receiver. The system further comprises at least one control unit configured to selectively activate the switches. The switches may be set to provide power from the power source to a portion of the plurality of the second coils or selectively increase or decrease the reactive power load of the power source.
