Synchronous Frame Control for Voltage Sag/Swell Compensator Utilizing Single-Phase Matrix Converter

抄録

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.
