N2 - In recent years, SiC switching devices have attracted attention because they can increase traction motor current and improve the motor performance compared with traction inverters using Si switching devices. Regenerative power is increased by improving motor performance, and there are examples that demonstrate the energy saving of railway vehicles has been achieved. However, the characteristics of the current and the loss of inverters applying both devices assuming specific applications, such as commuter trains, are unclear. Therefore, the trade-off relationship between motor performance improvement due to inverter current increase and inverter loss is unclear. In this study, the characteristics of the current and loss of the inverter are clarified, assuming the application of SiC switching devices.
