Abstract :
A power electronic VAr generator that provides reactive power compensation for symmetrical and nonsymmetrical nonlinear consumers is described. The control system provides inertial operation of the compensating system. By a stepwise change of the load current, some value of an active power is delivered by the VAr generator to the line during a few AC voltage periods. It is shown that this power electronic system can be used as an active filter for unwanted current harmonics reduction.<>
