What is the function of the inverter filter

Although most inverter filters from manufacturers are equipped with internal interference suppression devices, in some applications the use of external EMC filters is still required. The two EPCSEMC filters are ideal for external applications to frequency converters. With the continuous expansion of the inverter market, fierce competition, cost pressure and technological innovation have led to a continuous decline in product prices and shrinking quantities.
