Abstract

In this paper qualitative analysis and controller design of a TI-SEPIC converter for optimal utilization photovoltaic power is presented. This converter is essentially combination of conventional buck and SEPIC converters sharing common components. On the account of the integration load side only one inductor is sufficient enough for performing the power conversion in both Buck and SEPIC converters. Here the function of 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 converter performance is verified through PSEVI software simulations and then verified with measurement results obtained the laboratory prototype converter system.
