Abstract

The invention provides a fractional-order wireless power transmission system for offsetting internal resistors by using fractional-order capacitors. The fractional-order wireless power transmission system comprises a high-frequency power source, a transmitting circuit, a receiving circuit and a load, wherein the transmitting circuit comprises a primary fractional-order capacitor, a primary transmitting coil and internal resistors of a primary circuit which are connected in series; the internal resistors of the primary circuit are all positive resistors, including the internal resistor of the primary transmitting coil, of the primary circuit; the receiving circuit comprises a secondary fractional-order capacitor, a secondary receiving coil and internal resistors of a secondary circuit which are connected in series; and the internal resistors of the secondary circuit are all positive resistors, including the internal resistor of the secondary receiving coil, of the receiving circuit. Partial or complete offsetting of the internal resistors of the circuits is achieved by adopting series resonance of the fractional-order capacitors and the coils and simultaneously utilizing the property that each fractional-order capacitor has a negative resistor component within a specific parameter range.

Description

technical field [0001] The present invention relates to the field of wireless power transmission or wireless power transmission technology, in particular to a fractional-order wireless power transmission system that uses fractional-order capacitance to offset internal resistance. Background technique [0002] Wireless power transmission technology can realize complete electrical isolation between power supply and electrical equipment, and has the advantages of safety, reliability and flexibility. As early as the end of the 19th century, Nikola Tesla (Nikola Tesla) used the principle of wireless power transmission to light up the light bulb without any wire connection. The wireless power transmission based on magnetic coupling resonance is an MIT scholar. The breakthrough in the field of wireless power transmission has caused great repercussions in the field of wireless power transmission since it was published in 2007. More and more scholars have joined the basic research an...
