EMI Filters for Renewable Energy Applications


Alternate energy sources such as solar and wind energy have gained mainstream focus in the recent times as they are clean, efficient and renewable sources of energy. In Photo-voltaic generation, diodes incorporated in the solar cells convert light into a continuous electrical current (DC). In Wind Turbine generation, wind energy is converted into electricity by a mechanical turbine (horizontal or vertical) that rotates the electricity generator.


In both these renewable energy generation applications, the heart of the system consists of a power converter which transforms the electricity generated into AC mains frequency (50 or 60 Hz) used in industrial and residential applications. Electronic power converters are based on high frequency switching that generate electrical noise in both high and low frequency ranges.

EMI filters are designed and manufactured specifically for these applications to limit the noise generated to an acceptable safe level.

Many countries in the world have their own safety standards for EMI filters. So they should be selected based on what is approved by the safety standards of the countries to which the device will be exported.
