Patent

CA 2389137

The present technique utilizes already existing components within a variable speed drive to provide harmonic filtering characteristics. Particularly, the present technique integrates transformers and inductors to provide a filter within the variable speed drive. Further, the present technique may also utilize a sine wave filter to provide additional filtering of unwanted frequencies.

La présente technique utilise des composants déjà existants dans un variateur de vitesse pour offrir des propriétés de filtrage harmonique. En particulier, la présente technique intègre des transformateurs et des inducteurs pour assurer un filtre dans le variateur de vitesse. De plus, la présente technique peut également utiliser un filtre à ondes sinusoïdales pour assurer un filtrage supplémentaire des fréquences non voulues.
