Abstract

See full text

A static Voltage Ampere Voltage Reactive (VAR) comparator including: a plurality of capacitors being in a Y-connected structure and supplying three-phase alternating current power according to a switching operation; a plurality of bidirectional thyristors connected to the plurality of capacitors in serial to open and close the plurality of capacitors; and a controller, in response to power applied to the static VAR compensator, periodically applying a firing pulse signal to the plurality of bidirectional thyristors reaching to a voltage phase on which a transient current is minimized, wherein, at a point in time when first applying the firing pulse signal to one bidirectional thyristor, the controller applies simultaneously applies the firing pulse signal to the one bidirectional thyristor and other remaining bidirectional thyristors allowing a current to flow on three phases.
