Web1 jun. 2024 · Harmonic Filters for VFD There are 2 types of harmonic filters –passive harmonic filters and active harmonic filters. Passive harmonic filters utilize components like inductors, capacitors, and power resistors to filter noise on single variable speed drives before electricity reaches equipment with an electromagnetic field. WebVariable frequency drives draw current from the line only when the line voltage is greater than the DC Bus voltage inside the VFD. This occurs only near the peaks of the sine wave. As a result, all of the current is drawn in short intervals (i.e., at higher frequencies). Variation in variable frequency drive design affects the harmonics produced.
