An interleaved high step‐down coupled inductor based quadratic DC‐DC converter

A high step-down direct current-direct current (DC-DC) buck converter with a coupled-inductor in its topology is presented this study. The switching pattern of the proposed interleaved; therefore, voltage stress on semiconductors and components low since primary will be divided between blocking capacitors side. Thus, semiconductor elements low. As result, preselected can chosen ratings. In addition, there are cells coupled inductors utilized structure that helps to provide improved gain output terminal. Typically, narrow duty cycles needed achieve conventional converters, but has obtained conversion ratio even wider ratios. Besides, constant equation for whole range cycles. Theoretical analysis comparison other recent converters similar types have been conducted demonstrate performance. Furthermore, verify theoretical analysis, 600 W prototype 820 V/30 V implemented, experimental results presented.
