“…Thus, for FCEV is essential to step-up FC output voltage and regulate the electric voltage on DC bus, even if in case of battery system and ultracapacitors the level of electrical voltage is 250-360 V respectively 150-400 V [26,70]. The topologies of DC/DC converters are divided into two categories: non-isolated and isolated (See Figures 3 and 4) [71].…”

With the development of technologies in recent decades and the imposition of international standards to reduce greenhouse gas emissions, car manufacturers have turned their attention to new technologies related to electric/hybrid vehicles and electric fuel cell vehicles. This paper focuses on electric fuel cell vehicles, which optimally combine the fuel cell system with hybrid energy storage systems, represented by batteries and ultracapacitors, to meet the dynamic power demand required by the electric motor and auxiliary systems. This paper compares the latest proposed topologies for fuel cell electric vehicles and reveals the new technologies and DC/DC converters involved to generate up-to-date information for researchers and developers interested in this specialized field. From a software point of view, the latest energy management strategies are analyzed and compared with the reference strategies, taking into account performance indicators such as energy efficiency, hydrogen consumption and degradation of the subsystems involved, which is the main challenge for car developers. The advantages and disadvantages of three types of strategies (rule-based strategies, optimization-based strategies and learning-based strategies) are discussed. Thus, future software developers can focus on new control algorithms in the area of artificial intelligence developed to meet the challenges posed by new technologies for autonomous vehicles.

“…Isolated converters can offer larger step-up or step-down ratios and can allow for multiple DC outputs without significant cost [142]. Insulated converters can also improve efficiency, reduce switching losses, aid grounding, and result in low-voltage and current switching stress [143]. Non-isolated converters remove the transformers and use fewer semiconductor devices, which reduces switching losses, size, and cost, but they cannot provide large voltage ratios [141], the simplest topologies of which are buck, boost and buck-boost (Figure 14) converters.…”

This paper presents a complete review of MVDC applications and their required technologies. Four main MVDC applications were investigated: rail, shipboard systems, distribution grids, and offshore collection systems. For each application, the voltage and power levels, grid structures, converter topologies, and protection and control structure were reviewed. Case studies of the varying applications as well as the literature were analyzed to ascertain the common trends and to review suggested future topologies. For rail, ship, and distribution systems, the technology and ability to implement MVDC grids is available, and there are already a number of case studies. Offshore wind collection systems, however, are yet able to be implemented. Across the four applications, the MVDC voltages ranged from 5–50 kV DC and tens of MW, with some papers suggesting an upper limit of 100 kV DC and hundreds of MV for distribution networks and offshore wind farm applications. This enables the use of varying technologies at both the lower and high voltage ranges, giving flexibility in the choice of topology that is required required.

“…Thus, solar Photovoltaic (PV) energy harvesting systems have a remarkable growth and a significant penetration in many fields of application. In this paper, among the various applications of PV energy harvesting systems, we study a stand-alone Photovoltaic-battery-load system, classically based on the non-isolated two-stage DC-DC electronic conversion [1][2][3][4][5][6]. The rechargeable battery eliminates DC-link capacitor voltage stress; moreover, it allows energy storage for when the produced PV solar energy is larger than what is required by the load.…”

In this paper, a comparative analysis has been presented of two equivalent circuits of non-isolated buck/buck-boost converters under synchronous control, used in a stand-alone Photovoltaic-battery-load system. The first circuit consists of two cascaded buck and buck-boost classical converters with two controllable switches. The buck converter is used to extract the maximum power of the Photovoltaic source, and the buck-boost converter is applied for the output voltage level control. The second circuit consists of a proposed converter with a single controllable switch. In both cases, the switching frequency is used to track the maximum power point and the duty ratio controls the output voltage level. Selected simulation results and experimental tests confirm that the two conversion circuits have identical behavior under synchronous control. This study shows that the single switch converter has a lower size and cost, but it is limited in the possible control strategy.
