New family of non-isolated step-up/down and step-up switched-capacitor-based DC–DC converters

摘要

Here, a new family of non-isolated step-up/down and step-up switched-capacitor (SC)-based DC-DC converters are proposed possessing many advantages as lower voltage stress on capacitors and higher voltage gain compared to previously introduced DC-DC converters. The proposed converter structures have multiple capacitors which are based on principles of DC-DC SC converters. Therefore, the amount of power transfer from the input to the output is higher in the proposed converters. Generally, the proposed converters are more suitable for industrial applications, especially for generating high-voltage gains in lower duty-cycles. For proving the analysis, comprehensive comparisons and precise experiments have been performed which show remarkable performance of the proposed converter topologies.
