The major consideration in dc-dc conversion is often associated with high efficiency, reduced stresses involving semiconductors, low cost, simplicity and robustness of the involved topologies. In the last few years, high-step-up nonisolated dc-dc converters have become quite popular because of its wide applicability, especially considering that dc-ac converters must be typically supplied with high dc voltages. The conventional non-isolated boost converter is the most popular topology for this purpose, although the conversion efficiency is limited at high duty cycle values. In order to overcome such limitation and improve the conversion ratio, derived topologies can be found in numerous publications as possible solutions for the aforementioned applications. Within this context, this work intends to classify and review some of the most important non-isolated boost-based dc-dc converters. While many structures exist, they can be basically classified as converters with and without wide conversion ratio. Some of the main advantages and drawbacks regarding the existing approaches are also discussed. Finally, a proper comparison is established among the most significant converters regarding the voltage stress across the semiconductor elements, number of components and static gain.

A review of high voltage gain, high efficiency bidirectional dc-dc topologies is presented. Each converters primary benefit is highlighted, and a summary of all the converters is presented. It is observed that voltage gains higher than 20 is only achieved with topologies using a transformer. The average efficiency of the topologies is slightly lower for isolated topologies. Different strategies are utilized in most of the topologies in order to achieve the high voltage gain, and high efficiency, for example charge pumps, resonant circuits, coupled inductors, and switching cells.

“…A bidirectional dc–dc converter employing the 3SSC is shown in Fig. 6 d [23], which is able to operate in either buck or boost mode to achieve wide conversion range by modifying the turns ratio of the transformer, though operation in NOM is not possible. A similar structure associated to a family of bidirectional dc–dc converters for dc motor drives is described in [48].…”

“…minimised size, weight, and volume of filter elements, balanced currents through the converter legs, reduced current stresses, and improved distribution of losses with consequent minimisation of heat sinks. Among them, high-voltage step-up non-isolated dc-dc converters deserve special attention [16,[19][20][21][22][23][24][25][26][27][28], especially considering that most approaches typically found in the literature for this purpose are only feasible to lowpower levels. It is worth mentioning that the power levels that can be processed by 3SSC-based structures are also limited, though this issue was overcome with the introduction of the multi-SSC (MSSC) in [29].…”

The introduction of the three-state switching cell (3SSC) and the multi-state switching cell (MSSC) has led to the proposal of several converter topologies, where prominent characteristics regarding reduced dimensions of filter elements, high efficiency, and increase of maximum power levels are achieved. Even though the active switches associated to the 3SSC and MSSC are driven by signals obtained from multiple phase-shifted carriers similarly to the interleaving technique, there are significant differences between the aforementioned approaches. Within this context, this work intends to analyse several converter topologies employing the 3SSC and MSSC that were previously reported in the literature. An overview of important concepts regarding interleaved and 3SSC-based converters is initially presented, as potential advantages and drawbacks are discussed in detail. Besides, it is also shown how the 3SSC and MSSC can be employed in the conception of power converter topologies for distinct applications, e.g. high-voltage step-up non-isolated dc-dc converters, power factor correction rectifiers, and multilevel inverters.
