The switch power converters

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.

Talking point: Switch up. Lowering your cost of energy or operations is quite easy. 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. Talking point: Cut back more.

The same power modules inside the power cabinets can be used for different converters or different power drive types, enabling use of the same spare parts. The plug-in modules can be changed by the crew in only 15 minutes, making maintenance at sea as easy as possible.

This intelligent concept increases system availability and redundancy while enabling the elimination of an AC main switchboard. It lowers initial system investment cost and operational expenses over the long run. The Switch DC-Hub is built from our proven Power Drive units to provide a vessel with a flexible choice of power generation, energy storage, charging, propulsion power and clean power connected to the DC link, the backbone of the DC-Hub.

A DC-Hub consists of combinations of several basic elements. Of primary importance are the motor inverters to feed the motors from the DC link based on demand and the available power from the DC link. The propulsion motor can be virtually any type of motor, like an induction motor or a permanent magnet motor PMM. Using the power converter allows for precise dynamic control of power feeds and also meets stringent utility codes. The converter is UL certified as a grid interconnection device.

Additionally, the power converter greatly reduces any short circuit current contribution from the generator. The converter incorporates a generator and line inverter, with optimally designed filtering at both inverter ends to meet the highest standards for harmonics, flicker and fault ride-through FRT.

You can select from a series of modular full-power converters designed for grid-connected CHP applications in the range from to kW. Three power classes are available: — kW, — kW and 1 — 1.
