Abstract
This research offers a high step-up DC-DC converter using a two- winding coupled inductor and voltage multiplier circuit (VMC) including diodes and capacitors for renewable energy (RE) usages such as photovoltaic (PV) and fuel cell (FC). The advantages of this converter are: 1) High voltage gain with small duty cycle of the switch, 2) low voltage stress across switch/diodes, 3) Low number of components, 4) Lower volume and cost, 5) simple structure with only one power switch, 6) small current ripple of the input, 7) zero voltage and current (ZVS and ZCS) of the diodes, 8) improved efficiency, and 9) common grounding of the input and output. Due to the coupled inductor usage, the voltage gain is more flexible, and it can be enhanced by adjusting two different parameters: the turns ratio (N) of the coupled inductor and the duty cycle (D) of the switch. Furthermore, the voltage stresses of the semiconductors are decreased by increasing N. VMC is the other element for the power switch’s voltage stress reduction. The suggested topology could be an appropriate option for RE usage because of the small current ripple of the input and modified efficiency.
