由于组成复杂,现代电子设备正面临着日益严重的多场耦合问题。文中首先以电子设备中常见的电源模块为对象,分析了影响较大的几种典型耦合关系;其次为满足工程计算的需要,根据分析结果对耦合问题进行了必要的简化,设定电子设备中的耦合关系以两两耦合和线性弱耦合为主;同时还建立了电子设备多场耦合简化模型,并给出了采用序贯求解法的耦合求解算法;最后基于以上研究成果,建立了电源模块多场耦合问题的解耦仿真流程。

A Study on Uncoupling Method for Electronic Equipment Multifield Coupling Problem

Since the electronic equipment is becoming more and more complex,it faces serious multifield coupling problems.Power supply module,which is commonly used in electronic equipment,was taken as example to analyze several typical multifield coupling problems.To satisfy the need of engineering design,we simplified the coupling problem by assuming that the linear two-field coupling is the main coupling mode for electronic equipment.Based on this simplification,multifield coupling model for electronic equipment is obtained,and uncoupling method using direct coupling solution was given.At the end,an uncoupling simulation workflow for power module is established.
