چکیده :

In this article, a DC-DC step-up voltage topology for specific applications is presented. The propounded non-isolated configuration has merits such as achieving a high energy conversion rate with a low duty cycle and reducing voltage stress on the power switches. The theoretical analysis and operational modes of the circuit are discussed, and a comparative study with other non-isolated step-up DC-DC structures has been conducted to investigate the accuracy of its beneficial features, efficiency, and performance. To substantiate the theoretical discussions presented, the converter has been simulated in the PSCAD/EMTDC software, and the results are described.
