    Product description:

    Frequency converter special filter, that is, in order to eliminate the inverter, the power grid and other digital electronic equipment to produce interference spectrum component, the increase of frequency converter of the electromagnetic compatibility of specially designed filter.

    Frequency converter special filter is made up of inductor and capacitor low-pass filter circuit, it allows the useful signal by the current, the frequency of jamming signal has large attenuation. Due to the differential mode and common mode interference signals, so the filter to have damping effect of the two kinds of interference. There are three kinds of its basic principle:

    1, using the capacitance characteristics of high frequency isolation frequency will wire high frequency interference and zero line current through ground (common mode), or the wire high frequency interference current through the zero line (differential mode);

    2, the use of inductance coil impedance characteristics of the high frequency interference current reflected back to the interference sources;

    3, using the interference suppression ferrite can be certain of spectrum characteristics of the jamming signal is converted into heat, to choose the appropriate for a jamming signal frequency interference suppression ferrite beads, magnetic beads can be set on the need to filter the cable directly.
