“…As a result, the efficiency is improving, so the converter becomes ideal for use in situations requiring high gain when cascaded with a voltage multiplier. These features make converters suitable for high-power applications [56]. Employing the voltage lift and coupling technique with an interleaved quadratic boost converter increases the voltage conversion ratio.…”

In recent years, there has been a significant amount of literature concerning high step-up DC-DC converters. Whereas the voltage level needs to be raised to a higher value so that the DC conversion can meet the AC mains value. A boost converter is the most popular circuit in the field, but because of its drawbacks, employing it is limited. Interleaved boost converters have attracted considerable attention and are a promising solution for high-power step-up and power factor correction applications. To demonstrate the importance of this topology, a comparison has been made with single-switch converters. For this reason, this paper classifies the topologies into two main categories based on the number of main switching elements: Single-switch and interleaved boost converters. Then, each category was classified, including the conventional and the modified types, to cover the effect of adding voltage multiplier cells, coupled inductors, and a combination of coupled inductors and voltage multiplier cells. Each converter’s performance was evaluated by comparing the voltage gain of each unit. Also, this paper highlighted these converters’ essential characteristics, topological strategies, benefits, and demerits to clarify the differentiating solutions. Additionally, this work presents the difficulties or directions for developing novel topologies.

“…This topology consists of switches, diodes and inductors connected in parallel resulting in parallel connected quadratic boost converter as shown in figure 6. Interleaving of converters make them suitable for high power applications and results in better efficiency, fast switching, and output voltage with less ripple and reduced inductor current ripple allowing use of small size filters [23], [31], [32]. Authors in [23] use 40-57V, 2.5kW prototype for fuel cell applications and examined it for different structures of inductor, also the input of 40-57 (common in FC stacks) has been boosted to 400V using proposed converter.…”

Electronic devices require DC voltage for their operation so rectification (AC to DC conversion) is needed to convert AC voltage from the mains to DC. During this conversion, harmonics are generated in the system as well as power factor (PF) gets poor hence degrading power quality. Power factor correction (PFC) converters are being commonly used to increase PF and reduce harmonics. Boost PFC Converter is the mostly used topology for active power factor correction because of several benefits like series input inductor, high PF, but its voltage gain is not that good and it has output voltage ripple. Quadratic Boost PFC Converter can be used to overcome these two drawbacks by providing high voltage gain and less outputvoltage ripples. This paper represents applications and topologies of Quadratic Boost Converter, latest control techniques to achieve high voltage gain, regulated output and, high PF. Also, comparison is made between Boost Converter and Quadratic Boost PFC Converter. Finally, conclusion is made of this survey

“…Proposed converter comprises of two stages: first stage is interleaved boost stage and second is the voltage multiplier stage. Interleaving shares input current equally in parallel connected converters, reducing input ripple occurring in source, making converter input current magnitude more suitable for maximum power point algorithms [25]- [28] and second stage increases overall voltage gain of converter [29]- [31]. Hence the converter includes the advantages of both interleaving and Voltage Multiplier Cell.…”

In this paper interleaved quadratic boost converter with Dickson voltage multiplier is proposed. Photovoltaic system is connected to high power load through the proposed converter. Structure of this high gain interleaved converter comprised of two stages: interleaved quadratic boost converter stage and Dickson voltage multiplier stage. Interleaved quadratic boost converter is a parallel combination of two quadratic boost converter. The interleaving increases frequency of converter that could be filtered using small capacitors, making input current smoother than the current of conventional quadratic boost converter. Thus, interleaved circuit minimizes current ripple present in input current, cascading of voltage multiplier cell increases the gain voltage ratio of converter making it suitable for high power, high voltage gain photo voltaic applications. Stress voltage of the switches and reverse recovery problems gets reduced, thereby reducing EMI problems. 300W prototype capable of increasing 24V input voltage to 400V output voltage is designed and results tested using MATLAB/Simulink software. Hardware prototype is also implemented to verify simulation results. Also, application of this converter in integrated energy storage is demonstrated.
