Embodiment Construction

[0017] The present invention will be further explained below in conjunction with the accompanying drawings.

[0018] A distance optimization method for a dual-source wireless power supply system, the dual-source wireless power supply system such as figure 1 As shown, it includes two transmitting ends and one receiving end. The transmitting ends are respectively composed of a resonant capacitor, a high-frequency power supply and a transmitting coil in series. The parameters of the two transmitting coils Tx1 and Tx2 are the same and coaxially set. The receiving end is composed of a receiving coil Rx1, a resonant capacitor and a load. The size of the receiving coil is smaller than that of the two transmitting coils and coaxial with the transmitting coil. The position of the receiving coil can be moved between the two transmitting coils. Both transmitters can wirelessly transmit power to the receiver through magnetic coupling resonance, thereby supplying power to the load at the r...

Abstract

The invention provides a double-source wireless power supply system spacing optimization method based on minimum power fluctuation standard deviation. A wireless energy transmission device of a double-source wireless power supply system comprises two large transmitting coils and a small receiving coil. The optimal spacing between the two transmitting coils can be determined according to the given working frequency, coil parameters and load size, and the voltage of a high-frequency power supply can be further determined according to the size of load power. A double-source wireless power supply system obtained by the optimization strategy can provide power for loads at different distances under a fixed working frequency. The power fluctuation problem of the existing single-source wireless power supply system caused by distance change is solved. The method is applicable to the field of mobile device power supply.

Description

technical field [0001] The invention belongs to the application field of wireless power transmission technology, and in particular relates to a distance optimization method for a dual-source wireless power supply system. Background technique [0002] The development of wireless power transmission technology has significantly improved the spatial freedom of energy supply, and made it possible to remove the last cable (ie power cord) of electronic equipment. In 2007, the MIT research team proposed the magnetically coupled resonant WPT technology, which provides a new solution for the development of medium-range wireless power transmission technology. They use two coils with the same natural resonant frequency to transmit energy, which is different from traditional electric power transmission. Compared with the magnetic induction WPT, it can significantly improve the transmission efficiency of the resonator and effectively reduce the electromagnetic loss in the space. Once this...
