In this paper, development and performance characteristic of propulsion system(Converter/Inverter) using IPM(Intelligent Power Module) for 120㎞/h AC electric vehicle is proposed. The proposed propulsion system is comprised of IPM converter and inverter stack which uses natural air-cooling system, DC-Link, OVCRf unit and control unit. And also 2-Parallel operation of two PWM converter is adopted for increasing capacity of system and the VVVF inverter control is used a mixed control algorithm, where the vector control strategy at low speed region and slip-frequency control strategy at high speed region. The proposed propulsion system is verified by main line test results as well as combined test results. I

This paper introduces the propulsion system(Motor Block) stabilization test result for Korean High Speed Railway(HSR). The developed propulsion system using high power semiconductor, IGCT(Integrated Gate Commutated Thyristor) consists of two PWM converter and VVVF inverter. In this paper, overall configuration of propulsion system is briefly described and stabilization tests are made to verify the developed propulsion system. The presented test results shows beatless control method of inverter output current at the 200㎞/h and performance test of BCH.

In this paper, The Next Generation High Speed Railway inverter system based on IPMSM drives using Random Pulse Position Modulation is proposed to reduce electromagnetic noise. To verify the validity of study, the simulator for the proposed system is designed and impplemented. Simulation program is developed using Matlab/Simulink. The simulation results of the proposed system was compared with the system using conventional method. The results show that the voltage and current harmonics of the proposed Next Generation High Speed Railway Inverter system. significantly decrease and spread into wide band area by the proposed Random Pulse Position modulation technique based on Space Vector Modulation method.
