“…In [150]- [152], various combinations of quadratic boost and coupled-inductor techniques were used to achieve high voltage gain. Combinations quadratic boost converters with various VMCs can be found in [153]- [155]. With the aid of voltage multiplier circuits, the voltage gain of these quadratic boost based converters are high enough to fulfill high-voltage applications.…”

DC-DC converters with voltage boost capability are widely used in a large number of power conversion applications, from fraction-of-volt to tens of thousands of volts at power levels from milliwatts to megawatts. The literature has reported on various voltage-boosting techniques, in which fundamental energy storing elements (inductors and capacitors) and/or transformers in conjunction with switch(es) and diode(s) are utilized in the circuit. These techniques include switched capacitor (charge pump), voltage multiplier, switched inductor/voltage lift, magnetic coupling, and multistage/-level, and each has its own merits and demerits depending on application, in terms of cost, complexity, power density, reliability, and efficiency. To meet the growing demand for such applications, new power converter topologies that use the above voltage-boosting techniques, as well as some active and passive components, are continuously being proposed. The permutations and combinations of the various voltage-boosting techniques with additional components in a circuit allow for numerous new topologies and configurations, which are often confusing and difficult to follow. Therefore, to present a clear picture on the general law and framework of the development of next-generation step-up dc-dc converters, this paper aims to comprehensively review and classify various step-up dc-dc converters based on their characteristics and voltage-boosting techniques. In addition, the advantages and disadvantages of these voltage-boosting techniques and associated converters are discussed in detail. Finally, broad applications of dc-dc converters are presented and summarized with comparative study of different voltage-boosting techniques.

“…For demonstrating the performance of the proposed converter, Table 1 shows the performance comparison, in which the proposed converter is compared with the traditional zeta converter, the converter in [25] and the converter in [26]. Compared the converter in [25] with the proposed converter, the quantities of active switches and diodes are equal, but the voltage gain of the proposed converter is higher and the voltage stresses of the active switch and output diode are lower. Compared the converter in [26] with the proposed converter, the voltage gain and the quantities of active switches, the quantities of diodes are equal.…”

A novel non-isolated dc-dc converter topology for high step-up applications is presented in this study. The input side of the proposed converter can be derived with the help of a zeta converter, replacing the two inductors of basic zeta by a coupled inductor with double windings. At the same time, the switched-capacitor circuits are constituted through the secondary side of coupled inductor and diode capacitors, which enhance the voltage gain without a large duty cycle. The proposed converter can isolate the dc current from the electric source when it is switched off, and the voltage stress of the active switch is restrained through a passive regenerative snubber. Both the primary and secondary leakage energies of the coupled inductor can be recycled. The inrush current problem of diode capacitors is restrained by the leakage inductance of the coupled inductor. The above characteristics are the reason for the high-voltage gain and high efficiency of the converter. The principles of operation and steady-state analyses are described in detail. A compact circuit has been implemented in the laboratory, and the experimental results confirm the analysis of the presented converter.

“…It has the advantage of a smaller current ripple but suffers from high power losses due to more transformer turns. In [5], the converter has been developed by integrating quadratic boost with zeta converter to attain a higher voltage gain but requires two sets of magnetic cores that may increase the size of the converter. Non-isolated topologies do not use any HFT to provide higher voltage gain with reduced size and cost.…”

This article proposes a new high-gain converter to attain higher output voltage without coupled inductors. The operation of the proposed converter is examined under continuous conduction mode (CCM) and discontinuous conduction mode (DCM). Also, the mathematical expressions for the design of inductors, capacitors, voltage and current stress of semiconductor devices are provided. The proposed converter is simulated in MATLAB-Simulink and validated the effectiveness of the performance using a laboratory-based proto-type of 250 W at 50 kHz with a 60% duty cycle. The experimental results of the individual components are matched with the simulated results. Due to the continuous input current, the proposed converter is suitable for photovoltaic (PV) applications.
