Propulsion Controller
VVVF inverters have excellent reliability, maintainability, and energy-saving capability, and are ideally suited to a variety of applications such as conventional trains, subways, trams, AMP systems and High Speed Surface Transport, as well as electric locomotives.

Features
-
Speed sensorless vector control minimizes slip and slide, simple system configuration, dry-type capacitors, and ensures smooth riding comfort.
-
Compact size, light weight, and high reliability are realized with a simple configuration achieved with a two-level inverter using low-loss, high withstand voltage IGBT devices or SiC devices, and by adopting dry capacitors.
-
Life cycle costs have been reduced with a design that takes optimized lifetime and maintainability into consideration.
-
Due to IoT techncology on individual devices, conditions can be monitored and CBM requirements can be identified without the use of train information equipment.
- Indivisual or in-pallarel motor control can be selected depending on a train system or redundancy.
-
The cooling method (natural cooling or forced-air cooling) and enclosure shape (long enclosure, enclosure with integrated circuit breaker) can be selected based on the application and mounting space.
