High pass filter HPF
HPF filters are specially designed to remove harmonics from the current absorbed by 6 pulse power converters, such as frequency converters for motors, UPS, welding equipment, etc. They are essentially passive filters based on a series-parallel combination of inductance and capacitors. (Main function is to filter the 5th and 7th current harmonic and to decrease the level of the 11th and 13th current harmonics). With these HPF filters we will be able to get a reduction of the THD (I) level higher than a simple input reactor reduction, decreasing THD (I) to values below 8%. At full load conditions the THD (I) becomes lower than 5%.
