PWM MV7000 Converter and Induction Motor Solution: Major Step

Recent developments in IGBT (Insulated Gate Bipolar Transistor) components have opened up new vistas in power conversion. The use of press-pack IGBTs has helped design far more efficient converters.

Converteam has adopted this press-pack technology for the new MV7000 medium voltage PWM converters.

In combination with high torque density induction motors, these systems significantly enhance electric propulsion in terms of efficiency, ease of maintenance and low noise & vibration levels. There is no need for harmonic filtering and a powerful encoderless controller further optimizes the total power & propulsion plant design.

The high power density of the induction motors can enable slow speed direct coupled motors to replace medium speed motors and gearboxes.
