Discover how the SEMITRANS 10 MLI module perfectly meets the requirements of wind energy

3-Level Topologies for Wind Turbines by GD Rectifiers

Engineers are always looking at ways to reduce the cost of energy and increase the output power and new technologies make this possible.

3-Level Topologies for Wind Turbines

In regards to wind turbine developments, one solution is to increase the voltage up to the 10000VAC (1500VDC) low-voltage directive limit, which Semikron’s SEMITRANS 10 MLI, a 3-Level NPC module enables the engineer to do. Using 3-level topologies enables engineers to cut converter losses, cable losses or diameters can be reduced by around 30 percent.


Semikron is one of the world’s leading manufacturers of power modules and systems, primarily in the medium output range (2kW up to 10MW). Semikron’s product range is pioneering modern energy efficient motor drives and industrial automation systems. They also supply semiconductor products for power supplies, renewable energies (wind and solar power) and electric vehicles, including private cars, vans, buses, lorries and forklift trucks.


SEMIKRON’s innovative power electronic Seite 2 von 2 products enable customers to develop smaller, more energy efficient power electronic systems. These systems in turn reduce the global energy demand. Semikron is a family owned business founded in 1951, headquartered in Nuremberg, Germany. Today the company has more than 3,200 employees in 25 subsidiaries worldwide.
