Abstract
A device for automatic balancing of current and voltage of a three-phase system may be used for balancing current and voltage of unbalanced load in consumers’ three-phase electric mains. The device comprises a balancing unit, a phase current-to-voltage constant multiplier, a constant multiplier of phase voltage, a semi-balanced detector element, a single-chip microcontroller; a three-phase load is connected to a three phase source through the phase current-to-voltage constant multiplier. According to the invention two constant multipliers of phase voltage, two circuit changers, two subtracting units, a second semi-balanced detector element, and corresponding connections between said units are incorporated in the device. The invention provides improving accuracy of current and voltage balancing in case of nonsinusoidality due to use of active conductances in coordinate system (α, β) as informative parameters of a control system.
