随着电力电子技术和半导体制造工艺及制造技术的发展,IGBT现在已逐步取代晶闸管,被越来越广泛地应用到电动机驱动器中。但是由于它工作在高频、高压、大电流的环境条件下,使得IGBT很容易损坏。另外IGBT的可靠驱动也关系到整个驱动器的可靠性,IGBT的驱动和保护电路是电动机驱动器中的关键部分。 With the development of power electronics and semiconductor manufacturing processes and manufacturing technologies, IGBTs have now gradually replaced thyristors and are increasingly used in motor drives. However, due to its work in high-frequency, high voltage, high current environment, making the IGBT is very easy to damage. In addition IGBT reliable drive is also related to the reliability of the entire drive, IGBT drive and protection circuit is a key part of the motor drive.
