하이퍼튜브 추진용 케스케이디드 H-브리지 멀티레벨 인버터 설계

초록

This paper presents the propulsion system based on the cascaded H-bridge multi-level inverter for the HyperTube propulsion. Simulation results show that the proposed system has high efficiency under various modulation index condition of the inverter when compared to a two-level inverter and a three-level inverter. In order to confirm the feasibility of the proposed system as a HyperTube propulsion system, a miniature 5-level cascaded H-Bridge inverter is designed and test results show that such an inverter is expected to be useful for HyperTube based on long-stator linear motors.
