“…Renewable energy sources like fuel cells and solar PV have relatively low peak voltages, and high voltage gain converters are required to enhance and standardize the output voltage. For the past few years, many studies on DC‐DC converters have been conducted to attain high voltage gain 4,5 . All of these converters are classified into two types: non‐isolated converters and isolated converters.…”

In this paper, a non‐isolated switched inductor cell integrated high step‐up voltage gain DC‐DC converter with a charge pump mechanism is discussed. The continuous conduction mode of the input current is a beneficial aspect of this converter, which is appropriate for electric vehicles, renewable energy, and LED applications. The proposed converter works in two distinct operating modes and provides a flexible range of voltage gain ratios. The performance and small‐signal modeling of the converter in continuous conduction mode are extensively investigated, and voltage gain calculations for the two operational modes are derived. The Markov technique is used to evaluate the converter reliability, component failure rates, and mean time to failures. The proposed converter is evaluated with the existing converters in terms of voltage, and current stress of each component, voltage gain, total component stress factor, component count, and reliability. The proposed converter's hardware prototype has been developed. To validate the theoretical calculations, the converter's simulation and experimental results are discussed. The converter has a maximum output voltage of 110 V and a switching frequency of 50 kHz. The converter's peak efficiency is 94.5%.

“…Also, the power sources such as PV and wind need to extract the maximum power for efficient operation. To overcome this problem, an auxiliary DC–DC buck–boost converter will be necessary to control and stabilize the output voltage of the sources 5–11 . However, the converter should have continuous and low ripple input current, which is necessary to connect to renewable energy sources.…”

Nowadays, buck-boost DC-DC converters are widely used in numerous power devices. However, to have a suitable buck-boost DC-DC converter, reducing the input current ripple seems to be necessary. Also, having a lower current ripple at the converter output allows using low-cost, long-life ceramic capacitors instead of electrolytic capacitors. The presented buck-boost converter is made by interleaving two Cuk converters with positive and negative output voltage polarity, which provides the chance to eliminate the input current ripple at the selective duty cycle. The selective duty ratio can be determined by designing the inductors amounts at the input side of both converters. Though a new combination for the buck-boost converter is presented, which has zero input current ripple and low output current ripple which is obtained by output inductors. The converter maximum voltage gain is 2D/1-D and has easy control. In conclusion, a prototype model with 100-W output power is implemented, and the theoretical analysis and laboratory results are compared and validated.
