| Abstract: | A new kind of three-phase ac-ac converter with regulated output voltage or with output voltage variable continuously has been proposed. Cuk circuit, normally used in dc-dc voltage conversion, is employed in this converter with the help of three-phase electrical switches. Compared to the traditional ac-ac converter employ thyristors to regulate ac power, i.e. phase-controlled ac-ac converters, and existing line conditioners, this converter is smaller in size, higher in efficiency, less low-order in harmonics and larger in voltage adjustable range. The analysis of operating principle and control strategy of the proposed topologies are presented. Computer simulation and experimental resuh of the converter are also presented at the end of the paper. |
