摘要
Abstract
During the operation of shunt active power filter, the explosion of IGBT occurs several times. Through experiments the generation of IGBT over-voltage is analyzed. Because the shutdown time of IGBT is very short, the tiny stray inductance on the connecting wire produces a spike over-voltage under the effect of high frequency. The spike over-voltage affects the security of IGBT when it is superimposed on the original voltage. In this paper, the buffer circuit for an appropriate IGBT module used in the 100kVA shunt active power filter is designed, which solves the explosion problems and protects the safe operation of shunt active power filter.关键词
