摘要
针对电力机车的特点 ,设计了 5 0kVA绝缘栅双极晶体管 (IGBT)辅助逆变器 ,用于取代故障频繁的机车上原可关断晶闸管 (GTO)逆变器。自 1 996年 1 0月至今运行状况正常。从接地、屏蔽、吸收电路和减少引线电感等方面介绍了该逆变器的电磁兼容性设计。设计试验表明 ,5
The auxiliary IGBT Inverter rated 50kVA was designed to replace the GTO inverter which equipped to Electric Locomotive. The design of EMC considerations such as the configuration optimum, grounding, earthing, shielding and snubbing technique are presented. The experimental result shows that only a capacitor with low inductance is applicable as a snubber for IGBT invertors rated 50kVA.
