交流电感器的一种可视化设计方法

A Visualization Design Method for AC Inductor

针对交流电感器设计难以优化的问题,通过对交流电感器各约束条件如电感量、损耗、体积、温升等与电感器结构参数之间的关系进行分析,提出了一种基于四维可视化技术的交流电感器优化设计方法。通过分别优化电感器设计要求的各约束条件,取得最优区域的电感器结构参数求解域,然后在电磁场有限元分析软件中建立该结构参数的仿真模型,对电感量、最大磁通密度和温升等进行了评估;最后根据优化参数绕制了一个交流电感器进行实验。仿真与实验结论表明通过该优化算法,只需通过1次循环计算即可得到满足各约束条件的电感器,可避免磁芯电感器设计的盲目性。

Considering the difficulties of optimization in inductors designing, the relationships between the all constraint such as inductance,loss,volume and temperature rising conditions and parameters of AC inductor were analyzed, and an optimization algorithm based on 4D visualization technologies was preserted. Through optimizing the constraint condition of the inductor design requirements, respectively, the optimal domain of structure parameters was obtained. Then a simulation model was established on the finite element analysis software with the obtained parameters, to evaluate the inductance, the maximum magnetic flux density and temperature rise. The simulation and experimental results show that by the application of this optimization design method, only one circulating calculation is needed for getting the inductor matching all the constraint conditions, to some extent, so that the blindness of inductor designing can be avoided.
