摘要
电力功率器件IGBT的并联应用是提高功率变换器电流处理能力的重要手段,而如何处理在并联应用过程中出现的不均流问题成为能否实现实际工程应用的关键问题。在静态和动态两种工况下,分析了IGBT并联应用时影响其并联使用的主要因素及要注意的事项。给出了考虑这些因素影响后的实际并联应用的实验波形,波形结果表明并联功率IGBT器件的均流效果良好。
The application of parallel IGBT electric power device is an important means to improve the power con- verter current handling capability, and how to deal with in parallel in the application process of uneven flow prob- lems become key problems in practical engineering application. In the two static and dynamic conditions, the main factors affecting the parallel use of IGBT in parallel application and the matters needing attention are analyzed. The experimental waveforms of practical parallel applications considering these factors are given. The waveform re- suits show that the current sharing of parallel power IGBT devices is good.
