Project Description产品描述
High pass filter HPF
HPF高通滤波器
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%.
HPF滤波器是专门设计用来消除由6个脉冲功率转换器(如电机变频器、UPS、焊接设备等)吸收的电流中的谐波。它们基本上是基于电感和电容器的串并联组合的无源滤波器(主要功能是对五次和七次电流谐波进行滤波,并降低十一次和十三次电流谐波的水平。使用这些HPF滤波器,我们将能够获得比简单的输入电抗器降低更高的总谐波分布(I)水平的降低,将总谐波分布(I)降低到低于8%的值,在满负荷条件下,总谐波分布(I)变得低于5%。
