“…There are other effective methods to increase output voltage which have particular pros and cons [10][11][12][13][14][15][16]. Combination of switched-capacitor and switched-inductor techniques with the conventional converters are two of the methods that can be mentioned [13,16]. Also, interleaved configurations of DC-DC converters are used due to their advantages such as reduction of input current ripple.…”

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.

“…To overcome these problems, additional components like inductors, capacitors and diodes should be used as proposed in [5]. The other kind of extended converter based on boost is quadratic boost converter which consists of a reformed cascaded boost converter [10][11][12]. Its voltage gain is low and can be improved by adding a coupled inductor.…”

This study proposes a common grounded Z-source DC-DC converter. In comparison to conventional Z-source converter, it converts voltage with higher voltage gain and lower voltage stress on the switch, diodes and capacitors. In addition, it needs smaller inductors in comparison to the similar converters. The converter is analysed and compared with other converters. Its main equations are obtained which show the converter advantages as lower voltage stresses, smaller inductors, higher efficiency and higher voltage gain in comparison to the reviewed converters. A prototype for the proposed converter is prepared based on analysis and theoretical parts. Experiments are done along the lines of the analysis. Experimental results and theoretical equations are used to prove the converter operation quality.

“…The authors in Kaouane et al (2015) and Premkumar and Sumithira (2019b) reported converters with two MOSFET switches and hybrid boost, respectively, for solar photovoltaic (PV) systems to improve the output voltage gain along with the proper tracking technique. The quadratic buckboost converter was reported by Rosas-Caro et al (2018b) with the conversion output voltage and continuous input current with positive polarity.…”

The conventional DC-DC converters such as SEPIC, boost converter, etc. produces large voltage ripples in multilevel converter systems. For that reason, in this paper, a new DC-DC converter topology is proposed, and the performance is analyzed. Since the proposed converter delivers high conversion efficiency, it can be selected for multilevel boost DC-DC converters. The adverse effects such as inductor resistance and inductor size of the conventional converters are overcome by the proposed converter. The output voltage ripples are reduced in the proposed converter, i.e., the spikes in the converter output voltage are almost zero. The theoretical analysis is presented in this paper, which speaks about the advantage of the proposed converter. The converter operation is analyzed and discussed in continuous conduction mode (CCM). The voltage gain of the proposed converter is higher than the conventional boost converter. To validate the performance of the proposed converter, an experimental prototype is fabricated and tested in the laboratory. The performance of the converter is compared with the conventional boost and SEPIC converter. The experimental result confirms the theoretical analysis. The proposed converter can be extended by connecting more number of voltage multiplier (VM) cells to get the desired multilevel output voltage.
