Abstract

The invention discloses an optimization method and system of a wireless charging magnetic coupling device based on a genetic algorithm. The method comprises the following steps: S1, determining relevant parameters of a magnetic core influencing the output power and efficiency of the magnetic coupling device according to a wireless charging compensation circuit topology selected by a user; S2, obtaining a constraint condition to the size of the magnetic core; S3: taking the relationship between the relevant parameters and the magnetic core size, the relationship between the product of the window area and the effective cross-sectional area of the magnetic core and the magnetic core size, and the relationship between the volume of the magnetic core and the magnetic core size as the objectivefunction, and solving the magnetic core size satisfying the constraint conditions through the genetic algorithm; S4, judging whether there is a magnetic core size satisfying the preset index requirement in the magnetic core size satisfying the constraint condition, if so, executing S5, if not, executing S6; S5, outputting the magnetic core size which meets the preset index requirements; S6: obtaining the new constraint and repeating S3. The invention is advantageous in improving the electric energy transmission effect of the magnetic coupling device.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a genetic algorithm-based optimization method and system for a wireless charging magnetic coupling device. Background technique [0002] Autonomous underwater vehicle AUV (Autonomous underwater vehicle) is an important tool for exploring the underwater world. It is widely used in civilian and military fields. However, due to the limitation of its own size and battery technology, AUV cannot stay underwater for a long time. The work mainly adopts the method of recharging after salvage and recovery. This method is not only less intelligent, but also time-consuming and not convenient enough, which greatly reduces the working efficiency and concealment of AUV. Non-contact inductive power transmission technology, that is, wireless charging technology, can allow AUV to complete charging autonomously, quickly and efficiently, and is an ideal choice for underwater AUV power tran...
