Non-pulsed mode of supply in a three-phase system at asymmetrical voltage

摘要

Analizowano ortogonalna dekompozycję prądów trójfazowych w systemie z napięciem asymetrycznym dołączonym do asymetrycznego obciążenia. Prąd całkowity jest sumą składowej zrównoważonej i niezrównoważonej.%Two orthogonal decompositions of a total three-phase current are considered for a three-phase system with asymmetric sinusoidal voltage at the connection point of asymmetrical loading. In the first one the total current is represented as an orthogonal sum of balanced and non-balanced current components, the balanced component containing Fryze's active current (active power). In the second decomposition the total current is represented as an orthogonal sum of pulsed and non-pulsed current components. Both decompositions are used to create the optimal mode of supply with a constant instantaneous power at asymmetrical voltage.
