Abstract

A bridge arm winding type multi-phase flat plate magnetic core receiving end apparatus applied to wireless power supply of electric cars is disclosed, belonging to the technical field of wireless electricity energy transmission. The bridge arm winding multi-phase type flat plate magnetic core receiving end apparatus aims to solve the problems of lower coupling coefficient, worse side deflection capacity, higher magnetic field leakage amount, bad electromagnetic compatibility, higher manufacturing cost and bad electric energy stability between electric cars and guide rails existing in the current wireless power supply apparatuses. The bridge arm winding type multi-phase flat plate magnetic core receiving end apparatus comprises M*N bottom end flat plate magnetic cores, M connecting bridge arms and M*(N-1) coils; the bottom end flat plate magnetic cores are arranged in parallel at the equal intervals in sequence; the M connecting bridge arms crossover the Mth bottom end flat plate magnetic core, the 2Mth bottom end flat plate magnetic core, until the (M*N)th bottom end flat plate magnetic core in sequence; the M connecting bridge arms are arranged in parallel on the bottom end flat plate magnetic cores in sequence; the connecting bridge arms are in a comb-shaped structure; N vertical beams and one horizontal beam are connected uniformly in sequence to form a framework; the horizontal beam is divided equally into N-1 subsections by the N vertical beams; and a coil winds in the middle position of each subsection. The bridge arm winding type multi-phase flat plate magnetic core receiving end is applied to the electric cars.

Description

technical field [0001] The invention relates to a bridge arm winding type multi-phase flat magnetic core receiving end device for wireless power supply of electric vehicles, belonging to the technical field of wireless energy transmission. Background technique [0002] At present, there are two bottlenecks in the development of electric vehicles: the first is the battery used by electric vehicles, and the second is the charging infrastructure on the ground. In the prior art, batteries have many problems such as large volume, heavy weight, high price, scarce materials, poor safety, slow charging speed, and short lifespan. Moreover, the production process of batteries is high-pollution, resource-consuming, and ecologically damaging. process, which brings certain difficulties to the industrialization of electric vehicles. In view of the ground charging infrastructure problem, on the one hand, due to the long charging time, a large number of charging or battery replacement faci...
