( Abstract )
Interior permanent magnet synchronous motor is in the limelight as traction motor because it has advantages of miniaturization, reducing weight, and saving on maintenance costs. Because high-speed trains are large capacity loads, it is necessary to establish the design and development of inverter topology for driving IPMSM. NPC 3-level inverter has a high voltage rating and low harmonic, and can implement large capacity power conversion system. Also, it is easy to miniaturize and reduce weight because it does not need additional capacitors in comparison with other multilevel inverter topology. In this study, speed control of the IPMSM drives for the next generation domestic high-speed train system using 2-level inverter and NPC 3-level inverter is presented. Simulators of the system are implemented and simulations are performed. Finally, the designed systems are verified by comparison between simulations and experiments.
