Abstract
A new topology of the high step-up non-isolated DC-DC converter is illustrated in this paper. This topology adopts a modified voltage multiplier cell using coupling inductor. The high voltage gain of the proposed converter was achieved by minimum turn ratio and middle duty cycle. By low turn ratio, leakage inductance is low hence, stress of the active switch is reduced. Therefore, the conduction loss was reduced and the efficiency of converter increased. Another benefits of the proposed converter are low number of elements and continuous input current. By continuous input current, this converter can be used in renewable energy applications. Steady state analysis and all of the design procedure, investigated in this paper. Finally, operation of the proposed converter evaluated with simulation in PLECS software. The output power and voltage gain were selected 300w and 13.75, respectively.
