Abstract

The invention discloses a magnetic circuit mechanism contactless power transmission device, and relates to the technical field of contactless power transmission. A magnetic circuit mechanism primary side of the device is composed of a plurality of independent magnetic energy emission mechanisms connected in parallel. A magnetic circuit mechanism secondary side is composed of a plurality of independent magnetic energy pick-up mechanisms connected in series. The magnetic energy emission mechanisms are arranged on the running track of a locomotive, and the magnetic energy pick-up mechanisms are correspondingly installed at the bottom of the locomotive. The magnetic energy emission mechanisms and the magnetic energy pick-up mechanisms are of the same structure, and are composed of a receiving coil and a power conversion circuit. Each receiving coil includes at least two wound wire coils, each wire coil is connected with a rectifier module, and the rectifier modules output power. The device has the following advantages: the circuit topology is simple, and the power transmission ability of the system is strong; the magnetic cores of the pick-up mechanisms are not easy to saturate, and the pick-up mechanisms do not interfere with one another; the magnetic energy utilization rate of the primary side is high, and the system efficiency is high; and the device is suitable for providing high-power efficient energy transmission for a guide rail type contactless power transmission system.

Description

technical field [0001] The invention relates to the technical field of non-contact power transmission, in particular to a non-contact power transmission device of a magnetic circuit mechanism. Background technique [0002] The emergence of non-contact power transmission technology has solved the problem of safe, reliable and flexible power transmission in some specific environments. After nearly 20 years of domestic and foreign scholars' attention and research in this field, non-contact power transmission technology has made great breakthroughs in theoretical research, and has been used in non-contact power supply guide rail trams, fast non-contact power supply for buses, and smart human organs. Related products have been developed in the fields of external power supply, household portable device charging, and real-time power supply for underwater robots. In the rail-type non-contact power transmission system, the rail coil is usually a long straight wire, and the pickup co...
