Switch on new energy

The Switch is a leading supplier of megawatt-class permanent magnet generator and full-power converter packages for wind power and other new energy applications.

 

The Switch is a pioneer in tapping into the business potential of renewable energy resources as they become an increasingly more attractive and viable option for efficient electricity generation.

Customers use the company’s products and systems as part of their own machines or systems in wind turbine and other renewable energy applications, or energy conserving applications.

Steam recovery

Steam recovery is a growing area of interest for many industrial applications. Processes used in building systems and certain industrial production sites, such as ethanol plants for alternative fuels, produce excess steam, which often is wasted. By recovering this steam, customers can effectively use it for other power generation purposes.


Innovative grid connection

A growing trend, specifically in the building systems business, is the ability to interconnect local generating resources to the grid, rather than to have them as solely back-up devices. Yet most utilities do not allow the connection of a synchronous generator to its grid without a very elaborate and expensive approval process. It is somewhat easier to get interconnection permits for induction generators. However there is still concern about the short-circuit contribution from such a generator in case of a grid fault.

A converter-based system inherently offers interconnection capability while eliminating the short-circuit contribution to the grid.

The Switch’s strengths

The Switch offers a complete range of power converters using both air-cooled and liquid-cooled technologies.

Their inverters are built according to the latest interconnection standards, such as UL 1741 and IEEE 1547. The company provides the latest state-of-the-art features for the industry. These include micro-grid capability and seamless switching between grid-dependent and grid-independent operation modes.

The company also offer high-speed induction machines, which can be directly driven by certain high-speed steam turbines. This offers a viable generating solution from the turbine shaft all the way to the grid connection point.


Wide spectre of solutions

The company’s total generating solutions with air- or liquid-cooled power converter systems come complete with high-speed generators as applicable in a power range from 500 kW to 1 MW. These solutions provide unmatched interconnection features and capabilities. The range of AC-to-AC power converters for grid-connect operation extends from a few hundred kW to several megawatts.
