摘要
研制了一种针对大功率IGBT的驱动电路。对IGBT驱动电阻的位置进行了讨论,提出了一种新的IGBT开通、关断速度控制方式。驱动电路自身集成了开关电源。实验验证了该电路的各种功能,并给出了实验波形。
A driving circuit for great power IGBT is presented in the paper. This kind of diving circuit was paid a great attention in its electrical isolation and reliability when designing. This paper also discusses about the position of gate resister and presents a new method to control the turn- on and turn-off time of IGBT. an AC-DC converter as the functions were validated and at the last. This circuit integrates power supply. All the the waveform is given
