Here an improved three-level incorporated ac–dc converter is presented. This converter improving or boosting power factor correction. And also this converter topology is advanced than previous ac-dc converters for the most part the converter is functioning with two independent controllers which are combined in a single converter. Input controller does PFC and regulates dc bus, output controller regulates the output voltage. Converter function is explained and power factor is improved in this paper. Finally the efficiency of the new converter is compared with that of previously proposed converter. Simulation results are obtained using mat lab.
