“…Voltage sags or voltage swells occur due to the various operating regulation for voltage variations in distribution systems. For this aim, voltage sag supporters [1,2], voltage sag/swell compensators [3,4], DVRs (dynamic voltage restorers) [5,6], and voltage conditioners [7,8], are developed and applied successfully. The desired distribution network voltage is provided by these devices to the distribution buses where the AC loads are connected.…”

In this study, a switch-mode three-phase active tracking AC-AC voltage regulator based on the boost converter is proposed with a moderate number of active and passive elements used in the topology. A robust hybrid control, where a novel designed feedforward controller supports the closed-loop PID controller, is proposed for the control of the regulator apart from similar studies in the literature. Active tracking response of the reference output phase voltages is augmented by the proposed hybrid control method. Thus nearly close to sine-wave output phase voltages can be obtained, whether the input AC phase voltages are ideal pure sine or not. Also, the modular structure of the regulator topology enables independent control for each output phase. Thus, the supply of balanced/unbalanced wye-connected three-phase loads or independent single-phase loads with nearly close to ideal sine wave voltages can be achieved by the modularity of the regulator. Both experimental and simulation test studies are performed for the proposed regulator system. A laboratory set-up for the regulator is designed for 0-200 Vp input phase voltages (50 Hz), and 0-300 Vp output phase voltages, and 1.8 kW output power. The achieved results for both simulation and experimental tests verify the proposed switchmode boost-type regulator's ability to provide output phase voltages nearly close to sine wave with total harmonic distortion (THD) values under 5%.

“…In gridconnected inverters, methods to suppress the pulsations using feedback of filter capacitor current or filter inductor current were proposed (2) (3) . The authors investigated suppressing characteristics of pulsation of compensating voltage in the proposed system with stationary frame control (4) . It was shown that the pulsation of compensating voltage was not suppress enough for 40% voltage swell when only the inductor current feedback was applied.…”

In this paper, a synchronous frame control for a voltage sag/swell compensator utilizing single-phase matrix converter is proposed. First, the configuration of the proposed system and its operation are described. Next, the effects of the degree of voltage sag and load variation on the system stability are analyzed using the transfer function. Finally, the experimental waveforms of the system with the proposed synchronous frame control are compared with those of the system with a stationary frame control. The results demonstrate that the proposed synchronous frame control can suppress the steady state error and pulsation caused by the LC filter resonance better than the stationary frame control.
