چکیده :

This study proposes a new non-isolated high voltage gain topology. This converter has a continuous input current; hence, the input filter capacitor current stress has been decreased. The base of the topology of this converter is the combination of Luo and quadratic boost converters, so it’s available to reach a 10-times voltage gain with low duty cycle percentages. Moreover, the mentioned converter has one switch in its power topology, increasing the converter’s reliability. The ideal/nonideal scenarios for the mentioned topology have been discussed, and appropriate equations have been extracted. Eventually, the extracted simulation results from PLECS and the design assumptions were compared, and the extracted relationships were extracted
