摘　　要：目前,应用于风力发电机组中的绝缘栅双极型晶体管(IGBT)的功率等级较高,对IGBT的驱动保护技术的要求更高。文章着重介绍和分析了一种由分立元器件构成的过流保护电路,指出了该电路设计时应注意的问题。通过试验证明,在过流情况下该电路能可靠地关断IGBT,并输出故障反馈信号。Currently the Insulated gate bipolar transistor（IGBT） applied in wind turbine is in high power level,so the reliable drive protection technology of IGBT is needed.This paper focuses on a kind of over-current protection circuit constituted by discrete components and the issues we should pay attention to when we design over-current circuit.At last the experiment study on this circuit is carried out.The result show that this circuit can turn off IGBT reliably and give out fault feedback signal in an over-current condition.

关 键 词：大功率IGBT 过流保护 风力发电 软关断
