Title: SERIES COMPENSATED FRACTIONAL ORDER INDUCTIVE COUPLING WIRELESS POWER TRANSMISSION SYSTEM
Abstract:
A series compensated fractional order inductive coupling wireless power transmission system, comprising an emitting portion, a receiving portion, a voltage source connected with the emitting portion, and a load connected with the receiving portion, wherein the emitting portion comprises a fractional order inductance emitting coil, an emitting circuit internal resistor and an emitting end fractional order compensation network, and the receiving portion comprises a fractional order inductance receiving coil, a receiving circuit internal resistor and a receiving end fractional order compensation network. The fractional order inductance coil is used for inductive coupling to achieve wireless power transmission; the emitting end fractional order compensation network is connected in series to the emitting portion to compensate a reactive power of the system; and the receiving end fractional order compensation network is connected in series to the receiving portion to compensate the reactive power of the system. Flux linkage or voltage generated by the fractional order inductance coil is relevant not only to an inductance value but also to a fractional order of the coil, and the reactive power compensated by the fractional order compensation network is also relevant to an order of a fractional order component. The parameters are flexible in design and easy to be optimized.
