Abstract |
The paper deals with the current progressive balancing from the target of constant p or constant qcomponent of instantaneous power to symmetrical current target. Referenced current imbalancedepends on the operation mode and whether the current reaches the limit. The fixed p component ofpower is selected for the inverter operation mode. The fixed q component of power is selected for therectifier operation. In both targets, the current is sinusoidal, however unbalanced. It does not providethe maximum possible power transfer available at given voltage imbalance. The maximum power canbe reached at sinusoidal current. Thus in the case in which the current vector length reaches instantlythe maximum value, the current is progressively balanced to increase the value of transferred power.Symmetrical components decomposition based proposed control provides management of the semiminorand semi-major axes of elliptical hodograph of unbalanced |
