Abstract

In this paper a new integrated three-level ac/dc converter is presented. The proposed converter integrates the operation of the boost power factor correction and the three-level dc/dc converter. The converter is made to operate with two independent controllers - an input controller that performs PFC and regulates the dc bus and an output controller that regulates the output voltage. The input controller prevents the dc bus voltage from becoming excessive while still allowing a single-stage converter topology to be used. The paper explains the operation of the new converter in detail and discussed its features. Experimental results obtained from a prototype are presented to confirm the feasibility of the new converter.
