“…However, the output voltage of renewable sources is low and depends on environmental conditions. Therefore, recent developments in renewable systems, intelligent networks, hybrid vehicles, space equipment, and electronic devices cause the utilization of suitable high‐voltage gain dc‐dc power converters . Photovoltaic (PV) panels are one of the most efficient techniques for getting the greener energy to solve environmental problems caused by fossil fuels.…”

Summary In this paper, a new extendable high step‐up multi‐input‐single‐output dc‐dc converter is presented. The proposed converter is composed based on the conventional boost converter and conventional buck‐boost converter. The benefits of the proposed converter consist of the simple control of each duty cycle and low‐voltage stress across the semiconductors. Therefore, conduction losses can be reduced by using the switch with lower resistance rDS(on). The presented converter is flexible to obtain the high power level with the proper selection of duty cycle values. Therefore, the presented converter is controllable in different power levels of input sides. In fact, the proposed converter supports the operation of multiple input sources without any changes in the structure of the topology. The dynamic modeling and efficient multivariable controller design with dynamic responses for the proposed converter are analyzed completely. To confirm the performance of the presented converter, mathematical analysis and simulation results are presented. In addition, the comparison between the presented converter and some other topologies is provided. In order to illustrate the efficient operation of the presented converter, a laboratory prototype for a 425 V/300 W with 40‐ and 45‐V input voltages and 95.62% efficiency is implemented.

“…Photovoltaic (PV) panels are one of the most popular renewable energy generation systems, which directly convert sunlight into electricity. However, the generated voltage by PV panels is variable and low, which is related to the radiation and temperature . For this aim, high voltage gain and high‐efficiency direct current (DC)–DC converters are used to overcome the mentioned limitations.…”

“…Another group of high voltage gain DC‐DC converters is interleaved converters. Interleaving two boost converters and its combination with voltage multiplier cell, switched‐capacitor or coupled‐inductor converters enhance the voltage gain and reduce the input current ripple . However, the cost and size of these converters are increased, and the used controller circuit is complicated.…”

Summary The aim of this study is to propose a new nonisolated direct current (DC)–DC converter topology with high voltage gain and low voltage stress across the power devices. The proposed converter comprises a switch and n stages of inductor‐capacitor‐diode (L‐C‐D) units. Indeed, the proposed converter is based on the combination of the double‐boost and Single‐ended primary‐inductor converter (SEPIC), which is extended to n stages by adding L‐C‐D units. As a consequence, the proposed converter can generate higher voltage gains with small values of the switch duty cycle, which increase the controllability of the converter. Also, as the number of stages increases, the normalized voltage stress across the power devices is reduced. As a result, the Metal Oxide Semiconductor Field Effect Transistor (MOSFET) switch with low RDS‐on and devices with reduced nominal voltage can be used in the proposed converter. Furthermore, another advantage of the proposed converter is that the percentage of input current ripple is low. The voltage and current stresses of the power devices are analyzed. The circuit performance is compared with other high step‐up structures in the literature in terms of voltage gain and normalized voltage stress. The mathematical analysis and circuit performance of the proposed topology are verified by experimental results.

“…In this case, the ripple frequency regarding the input and output quantities is increased, resulting in reduced filter elements, minimization of current stresses through the semiconductors, and improved distribution of losses . However, current unbalance regarding the many phases must be carefully taken into account, what may be caused by small differences in the duty ratios applied to the active switches and/or parasitics with distinct ratings regarding the power stage elements . In this case, special control circuits and techniques may be necessary to achieve proper current sharing …”

Summary This work proposes the conception of a nonisolated direct current (DC)‐DC buck‐boost converter employing the three‐state switching cell. Similarly to interleaving, it is possible to achieve higher power levels than that regarding the classical buck‐boost converter, but prominent advantages over the interleaved approach result, ie, the input current is continuous for duty ratios higher than 0.5; good current sharing is achieved without the need of special control schemes; and the active switches are connected to the same reference node as the input voltage source, as there is no need to use isolated drive circuitry. A thorough quantitative and qualitative analysis is carried for the entire range of the duty cycle D, considering that the proposed converter presents distinct behaviors for D < 0.5 and D > 0.5. An experimental prototype is developed and evaluated, while the results are discussed in detail.
