Problems solved by technology

The multi-coil wireless energy transfer technology is conducive to breaking through the limitations of traditional single-channel wireless charging. Due to the mutual inductance between the coils on the same side, the current in the power device on the same side is affected, which will not only reduce the efficiency of the system, but also make the system It is difficult to control, so there is no practical application at present

Abstract

The invention discloses a modularized wireless charging system for decoupling coils on the same side. The system includes more than two power transmitters or power receivers. The power transmitter includes a driving power supply, a transmission compensation network and a transmission Coil, the power receiver includes a receiving coil, a receiving compensation network and a rectifier, characterized in that: the receiving coil or transmitting coil is placed in a single row, and each receiving coil and / or transmitting coil Correspondingly connect a multi-winding decoupler to eliminate the mutual inductance effect between receiving coils or transmitting coils on the same side, and realize the decoupling of receiving coils and / or transmitting coils; the present invention can be used to eliminate the mutual inductance between coils on the same side Therefore, it is of great significance to improve the transmission efficiency of the modular wireless charging system and reduce the difficulty of system control.

Description

technical field [0001] The invention relates to the technical field of wireless power transmission, in particular to a modularized wireless charging system that realizes decoupling of coils on the same side. Background technique [0002] Due to its safe and convenient features, wireless power transmission technology is widely used in various electrical equipment, such as mobile terminals, medical equipment, and electric vehicles. As a representative of high-power wireless charging applications, electric vehicle wireless charging technology has attracted much attention due to its advantages of high efficiency, convenience, low maintenance cost, and no environmental impact. Although the current low-power wireless charging technology has been developed to a certain extent, high-power wireless fast charging is still under study. The multi-coil wireless energy transfer technology is conducive to breaking through the limitations of traditional single-channel wireless charging. Du...
