风电变流器用1700V/2400A IGBT模块的开发与测试

Development and Test of the 1700V/2400A IGBT Module for Wind Power Converter

变流器是风电机组的核心部件之一,半导体功率模块是变流器装置的基础,其性能对变流器的性能和可靠性影响很大,是风电机组能否稳定可靠运行的关键因素。文章从风电变流器用IGBT的应用特点角度出发,主要介绍了某国产1 700V/2 400 A IGBT的芯片性能和模块设计情况、各项动态测试情况以及在风电功率组件中的考核情况。动静态测试结果表明,该模块不仅关断尖峰电压低、RBSOA区关断电流能力强,而且能够实现软关断特性与损耗之间的平衡。

Converter plays a key role in wind power systems. As the basic part of a converter, power electronic devices determine its performance and reliability, and are the key factors to decide if the wind power turbine can operating stable and reliable for tongtime. This paper mainly introduced the chip performances and module design of CRRC＇s 1 700 V/2 400 A IGBT, and its high suitability for wind power converter use. It also presented the IGBT dynamic test results and power test results that applied to power assembly. Dynamic and static test results show that the module has a good balance between losses and softness of module, lower overshoot voltage within the safe working area of RBSOA.
