Abstract
This paper studied on the VVVF Inverter for 1C4M propulsion system of railway traction. The paper includes the comparison along a VVVF Inverter electric power conversion element for an electric railcar(GTO, IGBT). These inverters are composed of high power IGBTs and controlled by compact control units. The stack is simplified and optimized by using plate bus and IGBT driver units of hybrid-type.
