چکیده

This study proposes a high step-up DC–DC converter based on quadratic boost converter. The proposed converter is composed of a quadratic boost converter and a multiplier cell. The converter can be used in low power applications which need to increase output voltage with high gain. In order to reduce number of the components, the multiplier cell is composed with the quadratic boost converter in a way to share one of their inductors. The found location of the multiplier adds some advantages to the proposed converter in comparison to the similar converters. The converter advantages include higher voltage gain, lower voltage stress on diodes and capacitors and requiring smaller inductors. To verify the points, principle operation of the converter is analysed and it has been compared with other converters. The proposed converter is designed and implemented using its main equations. Experiments are done along the lines of the analysis to prove that they have good accordance with each other. Operation quality factors such as voltage stress, voltage gain, efficiency, dynamic of the converter and operation in transient conditions are investigated using the experiments.
