Design of a Cost-Effective Non-Isolated Step-Up DC-DC Converter for Solar Systems

In this paper, a new non-isolated step-up DC-DC converter is proposed for solar systems. The proposed converter has simple topology, low volume, and lightweight because only one switch and one inductor is utilized. So, the control strategy will be simple. The design focuses on achieving high voltage gain and low voltage and current stress on semiconductors. Also, using the least number of elements in the structure is the other objective of this study. The proposed converter is investigated in continuous conduction mode (CCM), and the mathematical analysis has been examined in details. To confirm the theoretical concept, the proposed converter performance is examined, and the results are presented in detail.
