“…The battery's output voltage is several hundred volts of direct current (DC), and the EV's internal electrical systems, including the motor, audio, and video systems, heating, ventilation, and air conditioning (HVAC), lights, displays, etc., all require various voltage levels. The DC-DC Converter performs step-up or step-down operations depending on the voltage requirements [48], [49]. There are primarily two types of DC-DC converters.…”

Electric vehicles (EVs) are widespread, and their usage is increasing as a result of air pollution and rising fuel costs. EVs are quickly gaining popularity as a green means of transportation. By 2030, most cars will probably be battery-powered EVs. However, the development of EV power transmission is packed with important challenges and is an active topic of research. In EVs, the battery serves to store electrical energy. The DC-DC converter provides a direct current (DC) link between the battery and the inverter. A motor provides the transmission for the vehicle's motion. Hence, this state-of-the-art provides exhaustive information about battery management systems (BMS), power electronics converters, and motors. Lithiumion batteries are more efficient for EV applications, and boost converters and full bridge converters are commonly used in EVs. EVs use permanent magnet synchronous motors (PMSM) and induction motors (IM). The renewable energy-based charging station and the fast charging specifications are also clearly addressed for EV applications.

“…In the case of medium-and highvoltage systems, the need for galvanic isolation arises. This can be ensured using internal DC-DC converters based on high-frequency transformers, such as flyback and dual active bridge converters, connected to each submodule (SM) of the MMC [10][11][12][13].…”

The integration of photovoltaic (PV) modules with a modular multilevel converter (MMC) is very interesting because it allows us to exploit the intrinsic advantages of that converter, such as modularity and high voltage quality, and to implement distributed maximum power point tracking algorithms. The latter can appropriately be performed through controlling the circulating currents. In the literature, some control strategies for both the AC and DC circulating currents were proposed to manage the power mismatch among the legs and between the arms of the MMC. In a previous work, the authors proposed a novel control strategy for the circulating current components and inserted a capacitor on the DC side of a three-phase MMC with integrated PV panels. In the present work, it is shown how the correct sizing of this capacitor is essential to optimize the AC circulating voltages and minimize converter losses. A sizing procedure is proposed, deeply analyzed, and validated through numerical simulations.

“…DC-DC converters commonly been divided into isolated and non-isolated topologies. For isolated DC-DC converters high voltage transformers (HVT) are utilized as presented in [4,[20][21][22][23][24][25][26]. Typically, for such converters high gain voltage boosting can be attained by HVT with high turn's ratio and by using voltage multipliers [16,[27][28][29][30].…”

“…1 presents only the chief isolated and non-isolated converters. In order to connect energy sources offering lower input voltages with a DC -Bus at higher voltage, galvanically isolated DC-DC converters are one of the most promising options available [4,[20][21][22][23][24][25][26]. For such converters, this isolation protects the source from high voltage variations at the load.…”

In this paper, a comparative analysis has been presented on various topologies of isolated and non-isolated DC-DC converters. Here, the major focus remains on transformer-less (TL) DC-DC converters, based on the conventional basic boost converter. In addition, to attain high voltage gain, a classification of non-isolated converters based on extendable and non-extendable design has been presented. For comparative and theoretical analysis, the parameters chosen are the number of components utilized by each converter topology, high voltage gain offered, voltage stresses on each component involved and the efficiency of the high gain topologies. For the converters under discussion, operation under ideal and non-ideal conditions has also been highlighted. Based on this study, authors present a guide for the reader to identify various high voltage gain topologies for photovoltaic (PV) systems.
