Abstract

The invention provides a magnetic circuit optimization method, which belongs to the technical field of magnetic circuit design. The magnetic circuit optimization problem is established by mathematical modeling of the magnetic circuit, and the multi-objective particle swarm algorithm is used to solve the optimization problem, and the Pareto optimal solution set of the optimization problem is obtained. The optimal solution of the magnetic circuit. Compared with the traditional method, the present invention can select the non-dominated Pareto optimal solution, avoid blindly performing time-consuming and labor-intensive three-dimensional electromagnetic simulation, greatly speed up the design time of the magnetic circuit, and can achieve better magnetization level and lower current levels.

Description

technical field [0001] The invention belongs to the technical field of magnetic circuit design, and in particular relates to an optimization method of a magnetic circuit with a tunable magnetic field intensity. Background technique [0002] In electromagnets and microwave tunable magnetic devices, the design of soft magnetic circuits is involved. For example, microwave gyromagnetic materials will exhibit tensor permeability after applying a certain bias magnetic field. When electromagnetic waves act on microwave gyromagnetic materials, they will exhibit peculiar microwave characteristics due to the effect of tensor permeability. Since microwave gyromagnetic materials require a certain bias magnetic field to work properly, these devices all have bias magnetic circuits. This requires the design of the soft magnetic circuit to realize the application of the magnetic field. The traditional soft magnetic circuit design is to manually solve the magnetic circuit through the magne...
