Abstract

This paper presents a new integration concept to generate high voltage step-up non-isolated DC/DC converters with the aid of coupled-inductors. The integration concept relies on the separation of the converter circuit into two or three parts named input, middle and output sections. Hence, any basic converter can partially or fully share one of its sections with another basic converter since both circuits comply with the integration rules. The merged converters become an integrated topology with fewer components. According to this paper, for the input section parallel integration, the circuits remaining output sections can be associated in three different ways, in a series, parallel or cascaded connection. These output sections associations allow for a merged topology to enhance their voltage gain that becomes the sum of the voltage gains of the former topologies alone. An example of integration of the boost and flyback converter is provided to illustrate the theory. The resulting integrated topologies are theoretically and experimentally evaluated. The results prove that the integration methodology is an effective way to obtain high voltage conversion ratio circuits and that the derived topologies are highly efficient due to their low converter series resistances.
