N2 - In this article, a high step-up DC-DC converter based on DCL (Diode-Capacitor-Inductor) stages is introduced and explored. The first advantage of this topology is that the utilized DCL stages can be extended according to the required voltage gain. In addition, the voltage stress across the power switches and power diodes is low, which is another advantage of this structure. Considering these features, the proposed structure is applicable in renewable energy conversion systems. In this paper, a two-DCL-stage topology is garnered to increase the voltage gain. The voltage gain and voltage stress across the utilized components are calculated. In order to analyze the reliability of the proposed converter, the loss calculation and the effective parameters on the failure rates of the components are investigated. Also, a comparison of the introduced structure and some similar topologies is accomplished in order to prove its advantages. Finally, this converter is modelled in PSCAD/EMTDC simulation environment for 400W output power, to validate the theoretical computations, and the results are mentioned and analyzed in detail.
