 ABSTRACT 

This paper presents a study of two non-isolated DC-DC converter topologies with high static gain, basedon the association and integration of modified Boost and SEPIC converters. The associated topology usestwo controlled switches, while the integrated one employs only one. When performing the integration, theswitching cell known asR2P2is obtained. The proposed converters achieve high voltage gains ,making them suitable for applications where a reduced number of components is desirable, commonconnection between input and output, simplifying the control and command circuit. The paper presentsthe details of the derivation of the topologies and the operating principle including the topological stagesand main waveforms, in addition to the comparative analysis with similar converters previously proposedin the literature. To validate the analyses, two prototypes with a nominal power of 200 W, dimensionedto operate with an input voltage of 26 V and an output voltage of 260 V are presented. The convertersoperate at a switching frequency of 50 kHz, with an efficiency of 93.4 % for the associated converter and89.2 % for the integrated converter at rated power.
