N2 - In this article, an extendable high step-up DC-DC converter is proposed and investigated. The topology of the proposed converter is simple, and despite other similar structures, this converter does not implement switched-capacitor (SC) cells, switched-inductor (SI) cells, diode-capacitor-inductor (DCL) cells, or coupled inductors to enhance the voltage gain. In addition to the simple topology of the proposed converter, its high voltage-gain and reduced voltage stresses across the elements can be listed as the main advantages of this structure. In this paper, the proposed extendable high step-up converter is explained, and its operational modes are investigated comprehensively. The voltage stress across different elements and the voltage gain of the proposed converter are obtained. In addition, a 2-stage model of the proposed converter is designed for efficiency investigation and compared to other similar topologies. Finally, the designed 2-stage (25-400V, 500W) model of the proposed converter is simulated in PSCAD/EMTC environment to verify the theoretical analysis.
