Typically, high-frequency electromagnetic signals of 800KHz to 3.2MHz are generated. On one hand, these signals cause high-frequency resonance with parasitic inductance and parasitic capacitance; on the other hand, they can interfere with other instruments through conduction and radiation, especially high-precision ones. This is of great significance for thoroughly solving the high-frequency resonance and electromagnetic interference problems caused by high-frequency electromagnetic signals on the inverter side of frequency converters. Verified by over 1000 customers, the overall effectiveness rate of MLAD-SW sine wave filters for the above issues is ≥95%. 1.
