IGBT in Traction Inverters for Railway Systems

In modern locomotives powered by diesel-electric systems or fully electric operation, as well as EMU and DEMU vehicles using AC traction motors, advanced microprocessor-based AC-AC traction systems have become a key technological solution. These systems integrate IGBT-based traction converters with DSP and microprocessor-controlled embedded systems to deliver efficient and reliable motor control for railway applications.

The locomotive control system works in combination with IGBT-based traction converters to manage power delivery to the traction motors. Each traction converter can be configured with single or multiple inverters depending on system design requirements. These inverters may operate in independent axle control mode, where each inverter drives a single traction motor, or in bogie control mode, where multiple motors are driven together for coordinated performance.

Typical system configurations range from approximately 650 kW per inverter for bogie control applications to around 550 kW per inverter for independent axle control systems. Depending on the application, between 2 to 6 inverters can be integrated into a single traction converter, resulting in total power ratings between 1.3 MW and 3 MW.
