Optimal utilization of PV power by controlling TI-SEPIC converter

摘要

The controller design of a TI-SEPIC converter for optimal utilization photovoltaic power is presented in this paper and qualitatively analyzed. A combination of conventional buck and Single-ended, primary-inductor converters (SEPIC) sharing common components are essential in this converter. Only one inductor is sufficient for performing the power conversion in both Buck and SEPIC converters in the load side integration. Due to the lower SEPIC converter is to extract maximum power from the PV and feeds into the load, while the remaining load power demand is supplied by the DC source through a voltage-mode controlled buck converter. Proposed integrated derivative converter performance is verified through MATLAB and compared with a Proposed Integrated converter.
