摘要：

A new nonisolated high-step-up dc-dc converter based on active switched-inductors and passive switched-capacitors is proposed in this article. The main advantages of the converter are the high voltage gain (higher than 20), high efficiency, reduced voltage stresses, and reduced component count. This article approaches the principle of operation, theoretical analysis, design methodology, and a comparison of the proposed topology regarding other converters from the literature that use similar principles. Finally, the theoretical study is verified from a 200-W prototype designed to accomplish an input voltage of 20 V and an output voltage of 300 V, in which a peak efficiency of 96.2% is reached.
