A Novel Half Bridge Drive Circuit Applied in IGBT Module

摘要

A high performance and high voltage half-bridge novel IGBT driver circuit is described in this paper. The module integrates dual insulated driving and special protection circuits. It has high push-pull driving capability, bootstrap power supply technology and is easy for inverter miniature design. The paper also introduces the application in portable diesel engine generator and discusses some attention items in practical application. Experimental results show that this driving module has better performance and can reliably drive and protect IGBT.
