摘要

简要介绍了开关磁阻起动/发电机(SR S/G)系统的应用背景和工作原理。介绍了正在运行的30kW开关磁阻电机(SRM)及其变换器的结构和技术参数。在此基础上，对SRM及其变换器进行了详细的热分析。建立了瞬态集总参数热模型来预测SRM和转炉的热特性。为了使系统的最高温升保持在安全范围内，需要获得冷却系统所需的热性能，如最大热阻。这些性能对于冷却系统的设计、散热器的选择以及整个系统的优化都是非常重要的。

Thermal analysis of a 30kW Switched Reluctance Starter/Generator system used in aircraft

The application background and operating principle of the Switched Reluctance Starter/Generator (SR S/G) system are briefly introduced. The structure and technical parameters of an undergoing 30kW Switched Reluctance Machine (SRM) and its converter are described. Based on these works, the thermal analysis of the SRM and its converter are presented in detail. The transient lumped-parameter thermal models are built to predict the thermal characteristics of SRM and converter. To keep the maximum temperature rise of the system in a safe range, the required thermal properties of the cooling system, such as maximum thermal resistance, are obtained. These properties are very important for the design of the cooling system, the selection of the heat sink and the optimization of the whole system.
