This paper presents an ultrahigh step-up converter with combination of a quadratic boost converter, a multiplier cell, and a three windings coupled inductor. Main advantages of the converter include its high voltage gain, low voltage stress on the switch and most of the diodes, continuity of input current with low ripple, and existence of a common ground between the source and load. Furthermore, requiring small inductors leads to high efficiency performance of the converter. To confirm superiority of the proposed converter, it has been compared with the converters consisting coupled inductors. Analysis of the converter has been performed for its main operation modes to validate its quality and quantity factors. A prototype is built in order to experiment its performance per different conditions and evaluate the analysis. Rated values per the experiments are 25, 500, and 200 W for the input voltage, output voltage, and output power, respectively.
