Permanent performance for over 10 years 

We have challenged the wind industry, first by making permanent magnet generators (PMG) and full-power converters (FPC) the preferred technology for wind turbines, and now by enabling the technology to be commercially available. Our product portfolio covers all wind power applications from 1 MW to 8 MW and higher, including direct-drive, medium-speed and high-speed PMGs. Our FPCs are designed to work with our PMGs as a fully optimized drive train package.

Permanent magnet generators

The Switch PMGs provide excellent availability and productivity. Their specially segmented structure creates a group of redundant generators capable of independent operation to meet the latest power quality and grid compatibility requirements.

Full-power converters

The Switch full-power converters (FPC) have been designed specifically for wind power applications. They are optimized to work with a wide range of PMG concepts. Each converter series is built to best match specific wind conditions and the required turbine designs.

Third-generation packages

We are delivering our third-generation PMG and FPC packages with the broadest offering available. The Switch full-power converters are optimized to work with the entire range of PMG concepts. This ensures that you can effectively capture all power from highly variable sources of new energy.

Why PMG and FPC?

The majority of new wind turbine designs now coming to the market have all chosen permanent magnet technology.

Together, PMG and FPC simply lead to the lowest possible Levelized Cost of Energy and long-term permanent performance when analyzed from either a total life cycle cost efficiency angle or a reliability angle. That’s why we love PMG!

Lowering the cost of energy

Lowering your cost of energy or operations is quite easy. Simply lower overall capital investment costs, equipment lifetime operation and maintenance (O&M) costs, and fuel costs – while boosting the amount of energy generated.

This formula works even better with renewables – as the cost of wind, wave and tidal power, and solar is free! We are committed to improving annual energy production (AEP) and minimizing total life cycle costs (TLC), along with cutting back on operational costs.
