Abstract :
This paper presents a high voltage gain DC-DC converter. The proposed converter is based on the Sepic topology using the three-state switching cell. This converter is suitable for applications with a high voltage gain between the input and the output, as well as, UPS and renewable energy system. Another important feature of this converter is the lower blocking voltage across the controlled switches compared to similar circuits, which allows the utilization of MOSFETs switches with lower conduction resistances RDS(on). Principles of operation, theoretical analysis and design example of the proposed converter as well as experimental results for a 1 kW prototype are presented in this work.
