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

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 nonbalanced 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.
