The inductive components are said to feature low losses, low stray fields and a compact design. The chokes’ cores consist of powder composites specifically engineered for offshore wind turbines.
The materials developed by SMP have low magnetostriction, and low eddy current and hysteresis losses. Their encapsulated design ensures that the power converters emit only low-intensity stray fields, so that they do not affect other components.
SMP’s inductive components for wind turbine inverters are now certified IP66 and approved for use in offshore installations.
