IGBT驱动脉冲变压器工作过程分析及参数选择

The analysis of the working process of the IGBT's driving pulse transformer and the choice of parameters

详细地分析了IGBT驱动脉冲变压器的工作过程 ,讨论了影响驱动信号形状的因素 ,指出驱动电压信号应具有较缓的前沿、后沿陡度及合适的顶降 ,并在此基础上 。

This paper analyzes the working process of the IGBT's driving pulse transformer in detail and discusses the factors which inflluence the shape of the driving signal.It shows that the driving voltage signal should have relatively slow varying rates in the front and back edge,on this base of that,it makes a more reasonable choice of the main parameters of the pulse transformer.
