“…With renewable energy sources and embedded generation becoming more prevalent, many studies have pointed to EVs as means of mass-energy storage [52,53]. This has prompted the need for bi-directional topologies to facilitate the expedition of electrical energy from the vehicle into the grid [54,55]. This is principally achieved by replacing the secondary side rectifier with a full-bridge inverter, as seen in Figure 5.…”

This article classifies, describes, and critically compares different compensation schemes, converter topologies, control methods, and coil structures of wireless power transfer systems for electric vehicle battery charging, focusing on inductive power transfer. It outlines a path from the conception of the technology to the modern and cutting edge of the technology. First, the base principles of inductive coupling power transfer are supplied to give an appreciation for the operation and design of the systems. Then, compensation topologies and soft-switching techniques are introduced. Reimagined converter layouts that deviate from the typical power electronics topologies are introduced. Control methods are detailed alongside topologies, and the generalities of control are also included. The paper then addresses other essential aspects of wireless power transfer systems such as coil design, infrastructure, cost, and safety standards to give a broader context for the technology. Discussions and recommendations are also provided. This paper aims to explain the technology, its modern advancements, and its importance. With the need for electrification mounting and the automotive industry being at the forefront of concern, recent advances in wireless power transfer will inevitably play an essential role in the coming years to propel electric vehicles into the common mode of choice.

“…Among the innovative approaches to truly eco-sustainable mobility, the use of fuel-cells represents a notably valid solution, provided that green hydrogen is used [6]. The use of power electronics is also the basis for innovative electric vehicle (EV) charging methods, such as inductive power transfer (IPT), which makes it possible to wirelessly charge the storage system [7]. By means of reversible power electronics stages, the energy can also flow from the EV storage system to the grid, according to the vehicle-to-grid (V2G) concept.…”

In this paper, a DC-DC converter with an innovative topology for automotive applications is proposed. The goal of the presented power converter is the electrical storage system management of an electric vehicle (EV). The presented converter is specifically compliant with a 400 V battery, which represents the high-voltage primary source of the system. This topology is also able to act as a bidirectional power converter, so that in this case, the output section is an active stage, which is able to provide power as, for example, in the case of a low-voltage battery or a supercapacitor. The proposed topology can behave either in step-down or in step-up mode, presenting in both cases a high gain between the input and output voltage. Simulation results concerning the proposed converter, demonstrating the early feasibility of the system, were obtained in a PowerSIM environment and are described in this paper.

“…Because of their great thermal conductivity and wide bandgap, these ones can be exploited to get high power and to operate at high temperatures. These are the reasons why SiC plays an important role in the implementation of new technology applications, such as high efficiency DC-DC converters, DC-AC converters, inverters for solar and wind energy, photo-voltaic converters, power converters for electrical and vehicles, motor drives, power inverters for industrial equipment, high voltage switches for X-ray generators, thin-film coating processes, chargers and power supplies for renewable energy systems [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Many power devices are produced, such as Schottky barrier diodes, MOSFETs, power modules, IGBTs, BJTs, and many companies are engaged in making them.…”

In recent years, new efficient power devices have been implemented; in particular, Silicon Carbide (SiC) devices have advantages as regards their electrical characteristics, such as very low power losses, low gate charge, low capacitances, a low on-state resistance and many others, when compared to the Silicon (Si) devices; these devices can operate at high switching frequency and high voltages; with reference to their thermal characteristics, thanks to their great thermal conductivity, high power can be obtained and, because of their wide bandgap, high temperature can be reached; for these reasons, these devices are utilized in a wide range of technological applications, including power electronics. In this paper, power losses in Si and SiC devices are evaluated in simulation and compared to each other; in order to demonstrate the remarkable advantages of the SiC devices over the silicon ones, a study which makes use of an isolated DC-DC converter is proposed in this paper. As regards the proposed full-bridge converter, SiC and silicon MOSFETs and diodes, of whom some static and dynamic parameters are compared, are used in order to transfer power from a DC voltage supply to a load.
