Embodiment Construction

[0023] A method for designing equal-length receiving coils for efficient wireless power transmission, including a transmitting device and a receiving device.

[0024] Such as figure 1 Shown is the structure diagram of the system, the transmitting device includes a signal generator, a power amplifier, an adjustable capacitor C 1 and transmitting coil, transmitting coil with adjustable capacitor C 1 Realize series resonance; the receiving device includes a receiving coil, an adjustable capacitor C 2 and load, receiving coil with adjustable capacitor C 2 Series resonance is also achieved. The signal generator in the transmitting device generates a high-frequency signal with a fixed frequency, which is output by the power amplifier to drive the transmitting coil, and transmits the signal to the receiving coil through resonance, and then to the load.

[0025] The specific connection mode of the system is as follows: the signal output terminal of the signal generator is connecte...

Abstract

The invention discloses a method for designing an equal-length receiving coil for high-efficiency wireless energy transmission, which includes the following steps: (1) setting basic parameters: setting the basic parameters of the transmitting coil according to application requirements; (2) calculating the transmitting coil after the basic parameters are determined Length, in the case of ensuring that the coil lengths are equal, determine the optimal coil turn spacing of the receiving coil through calculation. Through the above steps, the transmission efficiency of the system can be improved by changing the coil winding method without changing the total length of the wire.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a design method for a coil of a magnetic coupling power transmission system. Background technique [0002] Wireless power transmission, also known as non-contact power transmission, refers to the transmission medium used from the traditional tangible medium to the intangible medium in the air during the transmission of electric energy from the power supply end to the electrical equipment, and there is no need for direct contact between the equipment. Contact, avoiding the safety hazards caused by electric sparks caused by friction caused by contact and line aging, has become a research hotspot in recent years. The application prospect of wireless power transmission technology is very broad. It can not only be used for household equipment and electric vehicle charging, but also can exert great application value in areas with special environments suc...
