“…15(a), only two active switches are used in an A-SL network and there is no need for an external switch in the converter circuit. In the recent literature [92], [93], converters that include this structure have often been called AN converters. ANs can be placed in a step-up dc-dc converter such as the one in Fig.…”

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.

“…Fig. 17(g) shows another AN [93], which uses two more diodes and two fewer passive components (capacitors) than the improved QA-SL. In this design, the voltage stress on the power switches is higher than in the improved QA-SL while the obtained voltage gains are identical.…”

“…Coupled inductor technology can be been seen as excellent candidate to achieve high voltage gain by changing the turns ration [9][10][11][12][13][14][15][16]. However, the passive lossless clamped circuit is introduced into the converter based on the coupled inductor, otherwise, a fearful switching dissipation and a serious spike voltage on devices are sure to arise because of the effect of leakage inductor [9].…”

“…The passive lossless clamped circuit can not only recycle leakage energy efficiently but also has no influence on the control system. Therefore, many converters with passive lossless clamped circuit and coupled inductor are proposed in [12][13][14][15][16][17]. In the clamped technique, it is composed of one capacitor and one diode.…”

In this study, a novel converter which integrates three capacitor clamped circuits and coupled inductor is proposed for high voltage gain. Compared with classical clamped circuit, these clamped circuits which are composed of one diode and three capacitors are used to improve voltage gain and achieve a continuous input current in this proposed converter. The proposed converter has four different clamped circuits, which can be divided into two types, including horizontal clamped and vertical ways. Moreover, each type of new clamped circuit corresponds to two different clamped circuits. This makes the designer have more selections to recycle the energy stored in leakage inductor. Besides, one of the three capacitors is connected in series with the output capacitor to efficiently reduce the voltage stress across the output capacitor, and voltages of both of them are less than half output voltage. Finally, in these converters, a converter based on three capacitor clamped circuit as a representative is analysed in detail. A prototype circuit is established in the laboratory to demonstrate the performances of this converter.

“…Interleaved Dual coupled inductor with voltage multiplier is designed in [16,17]. Switched Inductor based Active Network Converter (SL-ANC) is used to derive Coupled inductor based Active Network Converter (CL-ANC) and its performance is studied in [18]. However, the static gain of the converter is not much high compared to the other converters.…”

-This paper elaborates two novel proposed topologies (type-I and type-II) of the high stepup DC-DC converter using switched inductor and voltage multiplier cell. The advantages of these proposed topologies are the less voltage stress on semiconductor devices, low device count, high power conversion efficiency, high switch utilization factor and high diode utilization factor. We analyze the Type-II topologies operating principle and mathematical analysis in detail in continuous conduction mode. High-intensity discharge lamp for the automotive application can use the derived topologies. The proposed converters give better performance when compared to the existing types. Also, it is found that the proposed type-II converter has relatively higher voltage gain compared to the type-I converter. A 40 W, 12 V input voltage and 72 V output voltage has developed for the type-II converter and the performances are validated.
