“…The comparison is in terms of the voltage gain, steady-state electric stresses on circuit components, switching device power rating, and other features. Figure 15 shows the comparison of proposed converter voltage gain with a quadratic buck-boost converter [16], the enhanced gain buck-boost converter [17], a new quadratic following boost converter [18], a negative output buckboost converter [15], a continuous input quadratic buckboost converter [21], and a switched capacitor-inductor network-based boost converter [20], a high gain quadratic buck-boost converter [22], a switched capacitor cell extended modified cascaded converter [19], and singleswitch high gain quadratic boost converter [23]. Figure 15 shows that the proposed converter has a higher voltage gain than other converters except for the converter in [22].…”

“…Although this converter provides the high voltage gain with continuous input, there is no common ground between input and output terminals and uses more components. A switched capacitorinductor network-based dc-dc converter for high gain [20] uses a higher number of semiconducting power devices, and the controller design is complex as the converter order is very high. A new quadratic buck-boost converter is proposed to achieve the continuous input and high voltage gain [21].…”

This paper introduces the concept of inductors asymmetric input voltage to derive a new high voltage gain converter. The proposed converter has continuous input, positive output, and high-power density features suitable for renewable energy applications. The operating principle, steady-state performance, practical voltage gain, small-signal analysis, and efficiency of the converter are presented in this work. A comprehensive comparison is made with the high voltage gain converters available in literature in terms of component count, voltage gain, effectiveness index, voltage and current stress on the power devices, per unit switching device rating, and other features like output polarity and availability of common ground. The proposed topology possesses a higher effectiveness index and lower switching device power rating (SDP), resulting in a good form factor. To validate the performance of the proposed converter, the experiments are conducted on the 150 W laboratory prototype, and corresponding results are presented in this work.INDEX TERMS DC-DC converter, high voltage gain, quadratic converter, steady-state analysis, voltage stress.

“…In addition, the proposed converter has an interleaved structure that leads to a low input current ripple and low current stresses of the components. Thus, it was helpful to compare the proposed converter with two categories of existing high step-up converters: 1) non-interleaved quadratic converters, including both non-CI-based topologies in [16][17][18] and CI-based structures in [19][20][21][22][23]; 2) interleaved converters, including both non-quadratic converters in [24][25][26][27][28][29][30][31] and quadratic topologies in [32][33][34][35]. Thus, the proposed converter is compared to 20 existing converters in the literature to cover all aspects of comparison; 12 of them are quadratic high step-up converters and the rest is non-quadratic.…”

A new high step-up DC-DC converter for renewable energy applications is proposed in this paper. Employing an interleaved quadratic structure, two two-winding coupled inductors (CIs), and voltage multiplier cells (VMCs), the proposed converter can provide high-voltage gains, continuous input current with low ripple, reduced voltage stresses on semiconductors, common ground between input and output sides, and low numbers of components. In addition, diode-capacitor lossless clamp circuits are utilized to limit the voltage stresses of the power switches and further extend the voltage gain. The operating and steadystate analyses, design considerations, and a comparison with other previously published high step-up converters are presented.

“…These HGDC converters are used to integrate the low‐voltage sources, such as solar photovoltaic, fuel cell, battery etc., and deliver power to the load with high DC‐voltage gain. Apart from increasing the voltage gain, focuses are made to reduce the voltage and current stresses of various components of the converter [1–4].…”

“…Some of these converters utilise two or more switches [22]. The switch voltage stress is significantly higher in the converters reported in [3, 29, 30]. Certain applications require a converter with a fault ride‐through capability to produce the output voltage when there is a failure in the semiconductor switch.…”
