“…As shown in Figure A, for all values of the duty cycle, the converters in previous studies have higher voltage gain compared with the proposed converter. For D > 0.2, the converter has higher voltage gain in comparison with the proposed converter. For D > 0.5, the voltage gain of the proposed converter is higher than the converter .…”

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.

“…Active-passive inductor cells are integrated to increase the voltage gain. The inductor cells are replaced by switched inductor cells to increase the voltage gain [38]. However, this converter is operated with a single duty cycle, and the efficiency is severely affected because of repeated loops of energy transfer within the converter circuit.…”

A high number of research work is being carried out in the field of DC-DC converters to improve the performance of microgrid operation. The DC microgrid has a high level of acceptance because of the integration of renewable energy sources. In DC Microgrid, there is a need for improved DC-DC converter topologies which offer high gain, small size, enhanced efficiency, reduced voltage stress and reduced component count etc. A new Triple-Mode Active-Passive Parallel Intermediate Links (TM-A2P-IL) converter is proposed in the paper. The A2P-IL is designed by a combination of an inductor, capacitor, diode, and control switch. The proposed converter is derived by inserting A2P-IL in conventional boost converter. The proposed TM-A2P-IL converter operates in three modes and provides a high voltage gain without using a transformer, voltage multiplier stages, coupled inductor, switched inductor/capacitor circuitry. The other benefits of the proposed TM-A2P-IL converters are flexibility in the selection of duty cycles, reduced voltage stress of devices, small reactive components, single-stage power conversion. The proposed converter circuit, operating principle, steady-state analysis is studied for both CCM and DCM, discussed. The comparison between available similar type converters and the proposed converter is provided. The operation and performance of the proposed A2P-IL converter are validated through simulation and experimental work.

“…Recently, with the increasing application of high voltage DC power supplies, the high-gain step-up DC-DC converter has become more and more popular in many industrial fields. In general, DC-DC converters can be divided into two types: the isolated converter and the non-isolated converter [1,2,3,4,5,6,7]. The isolated DC-DC converter introduces an AC link where a transformer can be used to realize the isolation between the input and output.…”

A new type of DC-DC converter has been devised: the Hybrid Boost Inductor-Diode-Capacitor (HB-LDC) converter. A novel switching structure, a diode, a capacitor and a switch were added into an elementary additional circuit, to construct the HB-LDC converter. The proposed switching structure that carries out the step-up function is composed of three inductors and six diodes. The HB-LDC converter depends mainly on charging and discharging of the inductors and capacitors to realize the step-up function. The continuous-conduction mode (CCM) operation for the HB-LDC converter is analyzed. When the HB-LDC converter works in CCM, the voltage gain is only related to the duty cycle. Theoretical analysis shows that the HB-LDC converter is characterized by high voltage gain, low switching stress, and low inductance ripple. The theoretical analysis was verified by the construction of a working device.
