Abstract :
In this paper, two reduced parts single-phase unified power quality conditioners (UPQC) are introduced. These two systems consist of four or six power electronic switches instead of eight switches. The systems have the effective capability of line current conditioning as well as load voltage regulation. Control methods and analysis of these systems as well as the conventional four-leg system for different functions are presented. Simulation and experimental results are also presented to verify the theoretical analysis.
