Abstract

The thermal behavior of semiconductor devices of voltage source inverters for a traction frequency converter and its control systems are investigated. A test bed for studying thermal processes in steady state and transient modes occurring in semiconductor modules with air forced cooling systems is described. The results of an experimental investigation for the Infineon FF300R06KE3 module are analyzed and compared to the results of a mathematical model. Transfer functions of a semiconductor module as an object of temperature control are synthesized with respect to the collector current, cooling air flow, and frequency switching. The control system of thermal behavior of a voltage source inverter with two control actions on the object of temperature control (cooling air flow and frequency switching) is developed. It is proposed to use an electric drive with an induction motor and scalar control system for the purposes of regulating the cooling air flow. The effectiveness of the proposed control system is confirmed by means of simulation in MATLAB/Simulink in transient and steady-state modes.

控制电压源逆变器热行为的系统

摘要

研究了用于牵引变频器的电压源逆变器的半导体器件及其控制系统的热性能。描述了一种用于研究在具有空气强制冷却系统的半导体模块中稳态和瞬态模式下的热过程的试验台。分析了英飞凌FF300R06KE3模块的实验研究结果,并将其与数学模型的结果进行了比较。关于集电极电流,冷却空气流量和频率切换,合成了作为温度控制对象的半导体模块的传递函数。开发了一种以温度控制为目标(冷却空气流量和频率切换)具有两种控制作用的电压源逆变器的热行为控制系统。为了调节冷却空气流量,建议使用带有感应电动机和标量控制系统的电驱动器。所提出的控制系统的有效性通过在MATLAB / Simulink中以瞬态和稳态模式进行仿真得到了证实。
