A new harmonic current compensator composed of a static power converter was developed. It is composed of two voltage-type inverters in a multiplex configuration, this new compensator has a number of features that make it superior to the conventional passive filter composed of an AC reactor and a capacitor. This paper describes the principle of harmonic current compensation, the capability which the...
A novel scheme for four-quadrant thyristor-controlled static phase-shifters is presented. The technical feasibility of the proposed phase-shifter for damping power system torsional oscillations is examined. An optimization procedure is introduced to obtain the maximum damping for power system oscillations, by determining the optimum phase angle and magnitude of the phase-shifter out-put voltage. An...
The presence of parasitic capacitances in the power stage of a dc-to-dc converter designed for discontinuous-mmf operation results in a ringing of the mmf during the time that the mmf is intended to be equal to zero. With a constant-frequency controller, this ringing is shown to result in a widely fluctuating small-signal loop gain for relatively small changes in operating conditions. This fluctuating...
