AC-Choppers using instantaneous voltage control technique to solve voltage sag problems are proposed in this paper. The developed AC-chopper for series voltage sag compensation is applied for three phase four wire system; therefore, three single phase ac chopper circuits and three series transformers are utilized. By using AC-chopper, there are no required for a dc bus; thereupon, the size of proposed...
The aim of this paper is to present the application of three cells of a single phase ac-chopper interfacing with series injection transformer for compensating voltage sag in three phase four wire system. Each ac-chopper cell is independently controlled by instantaneous value voltage control technique. This technique is a comparison between the sinusoidal reference signal and the active triangle signal...
