摘要：

As buildings become taller, faster elevators are needed, and ultra-high-speed elevators need large-capacity power converters. We developed a converter circuit using four parallel-connected IGBTs. This paper explains the technique of balancing the current sharing of the four parallel-connected IGBTs. Especially, this paper reports the bus-bar assembly that reduces the imbalance of inductance between parallel-connected IGBTs. Furthermore, this paper reports the development of a common gate drive circuit and gate-wiring implementation. This balancing technique reduced the current unbalance caused by the assembly by 5%. © 2017 The Institute of Electrical Engineers of Japan.
