The invention discloses a fractional-order inductive coupling wireless power transmission system without a compensation network, which comprises a transmitting portion, a receiving portion, a voltage source connected with the transmitting portion and a load connected with the receiving portion, and is characterized in that the transmitting portion comprises a fractional-order inductive transmitting coil and a transmitting circuit internal resistor which are connected in series, the receiving portion comprises a fractional-order inductive receiving coil and a receiving circuit internal resistor which are connected in series, and the fractional-order inductive transmitting coil and the fractional-order inductive receiving coil realize wireless transmission of power through electromagnetic inductive coupling. The fractional-order inductive coupling wireless power transmission system performs inductive coupling by using the fractional-order inductive coils so as to realize wireless power transmission, magnetic flux linkage or voltage generated by the fractional-order inductive coils are not only related with the inductance but also related with the fractional order, the parameter design is flexible, optimization is performed easily, and the performance is completely different from that of a traditional inductive wireless power transmission system with integer-order inductive coils.
Description
technical field [0001] The present invention relates to the technical field of wireless power transmission or wireless power transmission, in particular to a fractional order inductive coupling wireless power transmission system without a compensation network. Background technique [0002] Over 100 years ago, Nikola Tesla demonstrated the feasibility of wireless transmission of electrical energy by lighting a light bulb without any wires connecting it. Since wireless power technology is a non-contact power transmission technology, which has the advantages of safety, reliability and flexibility, more and more scholars have devoted themselves to the field of wireless power transmission. [0003] At present, the implementation methods of wireless power transmission include: magnetic induction coupling, magnetic resonance coupling, electric field coupling, microwave, laser, etc. Among them, magnetic induction coupling wireless power transmission is extremely widely used in engi...
