- Abstract
Summary: This paper proposes a differential connection between the conventional boost and the mirrored SEPIC converters and the combination of them using switched‐capacitor cells. The integration results in a single stage power structure that provides high‐voltage gain and high efficiency. The article approaches a detailed static‐dynamic analysis and a comparison in relation to other structures presented in the literature. In addition, to corroborate the theoretical analysis and the operation stages of the proposed converter, a 200 W prototype, with a switching frequency at 50 kHz, an output voltage from 300 to 400 V and an input voltage of 20 V, is evaluated. An efficiency peak of 96.78% was reached at 100 W.
