绝缘栅双极晶体管模块温度的快速求解算法
Fast Algorithm for the Temperature of Insulated Gate Bipolar Transistor Module
摘要
Abstract
In the efficient thermal design of insulated gate bipolar transistor (IGBT) module,long-term reliability assessment of converter system,and several other aspects,IGBT module temperature usually need to be got.However,the existing models and methods are time-consuming and difficult to solve the IGBT module temperature quickly.Based on the idea of direct method,this paper presents a new algorithm for solving the temperature of IGBT module.The power loss model of IGBT module is built with the fitting and interpolation algorithm;the equivalent lumped parameters Cauer thermal network of IGBT module is studied and established based on the electric heating analogy theory,and the thermal differential equation is differenced;Finally,a fast algorithm for solving the temperature of IGBT module is constructed in the same circuit simulator.In two-level three-phase inverter example,with comparing to the IPOSIM simulation results,the maximum error of the proposed algorithm is 3.01％,and the trend of temperature change is basically consistent with that of IPOSIM simulation;with comparing to the simulation time base on traditional physics-based IGBT device model,thermal network component model,the algorithm proposed improves the computation speed by nearly 1 255 times.关键词
