Abstract
In this paper, an isolated high frequency link AC-AC converter for voltage compensation is proposed to maintain the quality of electric power in modern grid. The proposed converter can achieve arbitrary voltage output without any large electrolytic capacitors. Thus the system is more reliable and less costly compared with the traditional inverter-type solutions. Furthermore, the converter has no line frequency transformer, which also reduces the cost. The control scheme based on sinusoidal wave modulation technology is proposed to achieve better performance on voltage compensation, such as unbalanced voltage harmonics elimination. The converter and system configuration is introduced and the control strategy is described in details. The simulation and experimental results are given to shows the effectiveness of the proposed isolated high frequency link AC-AC converter and sinusoidal wave modulation technology.Keywords
