Basic circuit design of high step-up ratio DC-DC converter

Abstract

Thermoelectric power generation modules for industrial applications often require an output of several tens of watts, and DC-DC converters used for power matching are required to have high conversion efficiency at low voltage input. In this study, we realize high conversion efficiency at low voltage and we investigate basic circuit performance in the laboratory experiment. In addition, since some of the thermoelectric generation modules have low voltage output characteristics, it is necessary to design high step-up ratio DC-DC converter. In view of the above, we report on the design and trial evaluation of the generated power conditioning system with the high step-up ratio DC-DC converter.
