Abstract
Apparatus for power factor correction of alternating current networks in a continuous fashion. A first group of reactance devices are each serially connected to the network through a switching device, and a second reactance device is connected in the network through a control device for continuous control of the reactance provided by the second reactance device. A source of control signals responds to a signal determinative of the desired reactive power and controls the switching device for step-wise varying the reactance provided thereby and likewise controlling the control device for continuous control of the reactance contributed by the second reactance device to provide for overall continuous control of reactance as a function of the signal.
