Abstract

The invention relates to a bidirectional multi-freedom power adjusting vehicle-mounted wireless power transmission system, for power transmission of an electric automobile and a power network. The system comprises a controller, and a positive power transmission loop and a reverse power transmission loop which are of the same structure. The positive power transmission loop and the reverse power transmission loop each comprise a power source module, a boost / filter module, an inversion / rectification module and an electromagnetic conversion module which are successively connected, wherein the power source module, the boost / filter module, the inversion / rectification module and the electromagnetic conversion module are respectively connected with the controller. Compared to the prior art, the system provided by the invention has the advantages of multiple freedom, multiple control modes, high efficiency, large boost ratio, high flexibility, simple control system, two-way transmission and the like.

Description

technical field [0001] The invention relates to a vehicle-mounted wireless power transmission system, in particular to a vehicle-mounted wireless power transmission system with bidirectional multi-degree-of-freedom power regulation. Background technique [0002] The traditional wired charging method cannot realize the automatic charging of electric vehicles, which violates the convenience requirements of electric vehicle users. At the same time, the wired charging process will cause high-voltage electric shock hazards to the operator. Wireless energy transmission technology can just solve the above problems. A pair of magnetic energy transmitting and receiving modules are used instead of traditional wired cables to convert electrical energy into magnetic energy, then receive and convert it into electrical energy, and then charge it into the power battery. Wireless power transmission technology can realize a safe, convenient and fully automatic charging process, and has stron...
