Analysis and Implementation of different non-isolated Partial-Power Processing Architectures based on the Cuk Converter

Abstract

This paper presents the analysis and study of different partial-power processing architectures based on the Cuk converter. Thus, the non-isolated topologies analyzed have been considered operative as voltage source converter (VSC). Likewise, the study of the converters is based on the continuous conduction mode (CCM). The partial-power topology has some advantages, such as high power density, small size, the decreased voltage in semiconductor devices, etc., this is because the DC-DC converter only processes a fraction of the total power. The purpose has been to compare the different topologies, Full-Power, Partial-Power, and hybrid-converters, in order to observe the advantages and drawbacks in each case. Among the parameters to be studied is the voltage stress in semiconductors as well as the voltage gain in each architecture. The effectiveness of these new converter architectures has been validated by the Matlab/Simulink software simulation. In this way, different simulation results are presented and analyzed throughout the paper. The purpose of this paper has been to study and explore the usefulness of the non-isolated Cuk converter with partial-power processing architecture for industrial power applications.
