Description
Summary:This work presents a family of non-isolated high step-up dc-dc converters for high-power, high-current applications based on the multi-state switching cell (MSSC) and voltage multiplier cells (VMCs). Inherent advantages in the proposed topologies include reduced current and voltage stresses on the semiconductors, improved thermal distribution, good current sharing among the phases, and reduced dimensions of filter elements. Another relevant aspect is that the derived converters present modularity in terms of the possibility of extending not only the voltage gain, but also the rated power. A non-isolated dc-dc boost converter employing the four-state switching cell (4SSC) is thoroughly analyzed. Experimental results obtained from a 1.3-kW prototype are presented and discussed to validate the theoretical assumptions.
