چكيده فارسي :
Low and variable production voltage of renewable energy sources such as solar cells, fuel cell in terms of DC voltage range is always a big challenge in the field of connecting these sources to the power grid. In order to connect these sources to the inverter and then to the power grid, a DC-DC interface with the ability to convert the input voltage level to 230 or 400 volts is required. This converter should be a step-up DC-DC converter with high voltage gain. So far, many boost structures have been proposed to create a constant voltage due to the variability of the input voltage. In this research, a step-up DC-DC converter with high voltage gain is proposed using a voltage multiplier cell (VMC) and a coupled inductor. Main equations of the converter in steady state have been calculated and simulation of the converter has been done to verify the calculations.
