Traction drive IGBT modules
In modern electric and hybrid trains, Insulated Gate Bipolar Transistor (IGBT) modules are at the heart of every traction converter. These high-power devices transform electrical energy from the grid or onboard source into the precise voltage and frequency needed to drive traction motors efficiently and reliably.
Traction converters operate in demanding conditions, handling thousands of amperes, kilovolt-level voltages, and millions of switching cycles over their lifetime. Selecting the right traction drive IGBT module is essential to balance power, efficiency, and durability. A well-optimised device reduces conduction and switching losses, helping to improve overall system efficiency and reduce the cooling burden.
Rail traction systems must perform consistently across wide temperature ranges and under constant vibration and electrical stress. High-quality traction IGBT modules are designed for:
- High thermal cycling endurance and long power cycling life
- Low switching losses and robust short-circuit performance
- Reliable operation in harsh and variable environmental conditions
Dynex’s IGBT modules, rated up to 6.5 kV and 3600 A, feature advanced Trench-Gate technology to deliver high efficiency and thermal stability in even the most demanding traction applications.
Supporting long-term reliability
In the rail sector, components must remain serviceable for decades. By ensuring mechanical consistency, strong supply continuity, and backward compatibility, Dynex supports both new traction systems and retrofit programmes, helping operators maintain performance and reliability across the entire fleet lifecycle.
Powering the next generation of transport
From high-speed rail to urban transit, IGBT module selection directly influences the energy efficiency, safety, and reliability of traction drives. Choosing the right partner and; one with deep semiconductor expertise and proven traction experience; ensures that every train runs efficiently today and remains dependable for the decades ahead.
Selecting the right IGBT module defines how safely, efficiently, and reliably a train performs throughout its service life.
