摘要:
?为了实现开关电源性能特性的精确仿真分析,需要考虑温度与元器件之间的电热耦合效应,否则将无法准确模拟电源真实工作状态。提出一种基于 iSIGHT 平台的开关电源电热耦合建模与仿真分析方法。采用有限元仿真方法提取高频变压器分布参数,建立等效电路模型; 分析功率半导体器件工作特性受温度的影响关系,建立肖特基二极管和功率 MOSFET 的电热耦合仿真模型。以某开关电源为对象,分别建立电路仿真模型和稳态热场仿真模型,采用 iSIGHT 对电、热仿真过程进行集成,实现电热耦合仿真数据的自动化交互。该电热耦合仿真方法提高了电、热特性的仿真精度,可精确描述开关电源的性能特性与下位特性参数的关系,为产品优化设计提供了准确有效的手段。
Abstract:
?:In order to obtain accurate performance simulation of switching mode power supply ( SMPS), the electro-thermal coupling effect between temperature and components should be considered. Ignoring electro-thermal coupling effect may cause the simulation inaccuracy of SMPS. A method of SMPS electrothermal coupling modeling and simulation analysis was proposed based on iSIGHT platform. The equivalent circuit model of high-frequency transformer was established,and the parasitic parameters were extracted based on finite element analysis. Then the relationship between characteristics of power semiconductor components and temperature was analyzed,and the electro-thermal models of Schottky diode and power MOSFET were established. Based on these models,a SMPS was carried out as an example. The circuit simulation model and the steady thermal field simulation were accomplished. Then iSIGHT platform was utilized to assemble electric simulation,thermal simulation,and automated data interaction of elec-tro-thermal coupling simulation. The electro-thermal coupling simulation method can improve the simulation precision of the electric and thermal characteristics,and describe the performance characteristics accurately. It provides another way for product optimization design
