Energy-Efficient Chokes for Inverters in Wind Turbines.
January 23, 2009 -
Suited for inverters used in wind turbines, maintenance-free chokes may be constructed as single-conductor chokes, individual chokes, choke modules, or LC filters to accommodate specific applications. Optimized design lends to service longevity, while use of low-loss materials contributes to energy efficiency. Offered as chokes and filters for frequencies up to 200 kHz and current to 1,000 A, products can be used in power electronics, power generation, and instrumentation/control.

Energy-Efficient Chokes for Inverters in Wind Turbines - Maintenance-Free and Durable
Graben-Neudorf, Germany, January 2009. SMP introduces highly energy-efficient chokes for inverters in wind turbines. The low-loss chokes stand out through their maintenance-free design and long service life.
To meet the demand for ever more energy-efficient components for wind turbine installations, SMP has developed choke designs specially for inverters used in wind turbines. Their high energy efficiency is achieved through their compact design and through the use of low-loss materials. SMP's chokes are maintenance-free and have a long lifespan - a significant contribution to reducing the expensive maintenance of wind turbines.
"Today's wind turbines are more efficient than ever before. Until only a few years ago, the maxim for wind power was: it has to be cheap. The awareness that efficient installations can be highly profitable has grown only over the past few years", says Stefan Schauer, technical sales manager at SMP.
SMP chokes have now also been tested and approved for use in offshore installations.
For use in power electronics, power generation, and instrumentation and control, SMP supplies chokes and filters for frequencies up to 200 kHz and current ratings up to 1000 amperes. These inductive components offer a high energy storage capacity at low volume, reduced losses, good EMC characteristics and a cost-conscious design. Depending on their application, they are constructed either as single-conductor chokes for high-current applications, individual chokes, choke modules or LC filters. All SMP components are manufactured to customer specifications using in-house developed powder composites.
Company information:
SMP Sintermetalle Prometheus GmbH & Co KG develops and manufactures inductive components and magnetically soft materials, cores and mouldings. Based in Graben-Neudorf near Karlsruhe, Germany, the company was founded in 1982 by Vasilios Gemenetzis and today employs 180 people. SMP has become one of the key global suppliers of magnetically soft materials for industrial applications, serving customers throughout the world.
SMP's product range includes low-loss inductive custom components based on in-house-developed powder composites, such as filter, commutating, step-up converter, power recovery and single-conductor chokes. Many of its products are used in the railway industry. Several tonnes of SMP chokes, for example, are contained in the inverters for the three-phase asynchronous motors of the state-of-the-art ICE 3 units of the Deutsche Bahn. The market for inverters for photovoltaic systems - which feed solar energy into the electricity grid - is also experiencing strong growth.
Ever since the company's foundation, research and development has been a key aspect of the company's philosophy. For its innovation management, SMP received the Special Award of the TOP 100 initiative, which distinguishes Germany's hundred most innovative medium-sized enterprises.
