    Tips: What is an EMC filter for variable frequency drive (VFD)?

    The special filter for variable frequency drive is a filter specially designed to eliminate the frequency spectrum components that interfere with the power grid and other digital electronic equipment and enhance the electromagnetic compatibility (EMC) of the VFD when it is working. The EMC filter for VFD is composed of a low-pass filter circuit made up of an inductor and a capacitor, which allows the current of the useful signal to pass, and has a larger attenuation for the interference signal with a higher frequency.

    The filters for variable frequency drive can be divided into VFD input filters and VFD output filters based on their use positions.
    1. Characteristics of VFD input filters

    • A wide range of attenuation characteristics;
    • Small leakage current.

    2. Characteristics of VFD output filters

    • dv / dt suppression, over-voltage limitation;
    • Reduce the electromagnetic interference of the VFD;
    • Reduce the loss of VFD and motor coil.
