This paper studied on the VVVF Inverter for 1C4M propulsion system of railway traction. The paper includes the comparsion 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.

This paper presents the current-fed inverter of a Korea Train express with thyristor switches using phase control and commutation techniques. A techonology can ensure the synchronous motor drive control that used the existing GTO element through synchronous motor controls of an inverter oh-type propellant for the high-speed railway vehicle which used IGBT and Thyristor together various system technology development and electric current that I develop a device, and used domestic technology.
