A single-phase, three-level, single-stage power-factor corrected AC/DC converter operated under closed loop manner is presented. That operates with a single controller to regulate the output voltage and the input inductor act as a boost inductor to have a single stage power factor correction with good output response. The paper deals with a new single stage three level ac-dc converter which performs both power factor correction and voltage regulation in a single stage. The proposed converter has two separate controllers, one for power factor correction and the other for regulating the output voltage. A comprehensive review of the existing single stage topologies has been carried out. Then the operating principle, control scheme and the design of the new converter are presented. The proposed converter is having an input power factor close to unity and better voltage regulation compared to the conventional ac-dc converter topologies. Proposed topology is evaluated through Matlab/Simulink platform and simulation results are conferred.
