German-based manufacturer Sintermetalle Prometheus GmbH & Co KG (SMP) will display its latest range of chokes for frequency converters and other drive technology applications at PCIM Europe 2017, May 16-18. The compact, low-loss, powder composites chokes are reported to have a space-efficient design and good electromagnetic capability characteristics.
The new compact chokes have been installed in frequency converters at the input, where they provide power recovery, and at the output, where they act as filter chokes. They have also been installed in frequency converters at the internal DC links, as both single and common-mode chokes.
The components incorporate an efficiency-increasing core of powder composites with low magnetostriction, while an encapsulated design ensures that the components emit only low-intensity stray fields- a requirement in frequency converters which allows other components to be placed in close proximity to the choke without the risk of magnetic interaction with the choke.
The new compact chokes use in-house developed powder composite materials with a reported saturation induction of up to 2 Tesla. They are available in dimensions ranging from 19 mm-300 mm and weighing from 0.05 kg-130 kg, and up to temperature class H (180°C). Depending on the application, protection classes up to IP66 are available. All components are RoHS and REACH compliant and CE and EAC certified, and the materials used are UL-listed.
SMP was founded in 1982 by Vasilios Gemenetzis and today employs about 150 people. With a key focus on research and development, 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.
