“…Various high step-up gain DC-DC power electronic converter structures belonging to isolated and non-isolated categories were suggested and reviewed in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. All isolated converter configurations involve the use of transformers whose turns ratio can be adjusted to increase the DC output voltage level of the converter.…”

There are different low switching stress non-isolated DC-DC power converter structures developed for Photo-Voltaic (PV) applications with a view to achieve high voltage conversion ratio. The work proposed in this research article investigates the performance analysis of a coupled inductor and diode-capacitor multiplier cell based non-isolated high gain single-switch DC–DC conversion scheme with a single-ended primary-inductor on the input side. The presented converter suitable for renewable energy applications has the merits such as continuous input current, high voltage conversion ratio, and reduced voltage stress across the power switch. The multiplier cell consisting of two diodes and two capacitors is mainly used to enhance the converter output voltage level. A MATLAB / SIMULINK model of the suggested topology has been developed to validate its performance. During the simulation of the converter, a DC voltage of 50 V was given at the input side. The load end received a DC voltage of approximately 900 V. Thus, through this study, it was found that the addition of diode-capacitor cell can significantly improve the static gain of the suggested converter. The findings of this research may serve as a base for future studies on improvement of voltage gain of DC-DC converters.

“…There is another possible solution for improving the DC voltage gain of the converter using switched inductor (SI)based DC-DC conversion technology, which employs parallelcharge and series-discharge inductors (Yang et al, 2009;Gautam, Sharma, & Shukla, 2019). This switched inductorbased converter configuration can operate in boost mode as well as in buck-boost mode.…”

The conventional power electronic boost converters have inherent limitations that they are not able to increase the low DC input voltage level into sufficiently high DC output voltage level. This is because of the fact that (1). the inductor used in the converter has certain amount of internal resistance, and (2). the power devices used in the converter are subjected to high potential stress which led to damage of the devices. A configuration of a non-isolated step-up rectifier-fed positive output power converter capable of converting low DC voltage into high DC output voltage-based on the concept of parallel-charge series-discharge inductors is proposed in this paper. The proposed converter is fed by an uncontrolled diode bridge rectifier to which an input sinusoidal AC voltage of magnitude 30 V (rms) is given. The converter is configured such that the input AC voltage of 30 V (rms) is stepped-up to around 900 V (DC) at the output of the converter, with extremely low duty ratio. The proposed converter configuration employs only two high power semiconductor switches with reduced complexity of control. In this work, the converter topology is presented, and its steady state behavior and dynamic modeling are discussed for continuous inductor current mode operation. Further, it is revealed that the voltage gain of the converter is influenced by the variation of the duty cycle of the power switches. The effectiveness of the converter is better understood through simulation in MATLAB/SIMULINK platform. The results demonstrate that the converter is able to maintain higher constant output voltage profile with significantly reduced overshoot and settling time.
