철도차량 전동기 드라이빙 효율 증대를 위한 SiC 전력용 반도체 기반의 2레벨 3상 인버터의 손실 특성 비교

Comparison of Loss Characteristics of 2-Level 3-Phase Inverter based on SiC Power Semiconductor to Increase Driving Efficiency of Electric Motors in Railway Vehicles

초록

The purpose of this paper is to compare and analyze the loss of propulsion inverter using SiC and Si power semiconductors for high efficiency of railway vehicles with renewable energy. Accordingly, loss comparison and analysis were carried out through PSIM Thermal Module and Loss Modeling with a SiC-MOSFET module and Si-IGBT Module. As a result, 2-level 3phase inverter using SiC-MOSFET module had extremely low switching loss compared to propulsion inverter that using Si-IGBT module. If SiCMOSFET module is used in propulsion inverter of traction motor for railway vehicles, it is considered to be advantageous for high efficiency
