“…This leads to a surge in demand for off-board charging, which can provide higher charging power from the grid. Off-board charging applications have similar demand for charging efficiency to OBCs and a typical DC fast-charging station comprises a front-end rectifier with Power Factor Correction (PFC) and a back-end isolated DC/DC converter [46]. The application of SiC MOSFETs provides possibilities for charging stations to improve efficiency up to 98.2% [47], reduce total losses by 24% [48], improve dynamic performance [48], reduce size [49], reduce magnetic and cooling system costs [50], and increase charging speed [51].…”

Compared with silicon‐based Insulated Gate Bipolar Transistors (IGBTs), silicon carbide (SiC) Metal‐Oxide‐Semiconductor Field‐Effect Transistors (MOSFETs) are characterized by higher operating temperatures, switching speeds and switching frequencies, and are considered the next evolutionary step for future electric drives. The application of SiC MOSFETs in the field of electrified vehicles has brought many benefits, such as higher efficiency, higher power density, and simplified cooling system, and can be seen as an enabler for high‐power fast battery charging. This article reviews the benefits of SiC MOSFETs in different electrified vehicle (EV) application scenarios, including traction inverters, on‐board converters, and off‐board charging applications. However, replacing Si‐IGBTs with SiC MOSFETs introduces several new technical challenges, such as stronger electromagnetic interference (EMI), reliability issues, potential electric machine insulation failure due to high transient voltages, and cooling difficulties. Compared to mature silicon‐based semiconductor technologies, these challenges have so far hindered the widespread adoption of SiC MOSFETs in automotive applications. To fully exploit the advantages of SiC MOSFETs in automotive applications and enhance their reliability, this paper explores future technology developments in SiC MOSFET module packaging and driver design, as well as novel electric machine drive strategies with higher switching frequencies, and optimized high‐frequency machine design.

“…The AFE rectifier system can also be implemented using the emerging SiC MOSFETs as a substitution of Si IGBTs. The SiC-based AFE rectifiers are demonstrated in [39,40]. One unique feature of the SiC-based B6-AFE rectifier is that the SiC MOSFET can be operated under the synchronous rectification mode by its channel reverse conduction, which features low conduction loss.…”

Renewable power-to-hydrogen (P2H) technology is one of the most promising solutions for fulfilling the increasing global demand for hydrogen and to buffer large-scale, fluctuating renewable energies. The high-power, high-current ac/dc converter plays a crucial role in P2H facilities, transforming medium-voltage (MV) ac power to a large dc current to supply hydrogen electrolyzers. This work introduces the general requirements, and overviews several power converter topologies for P2H systems. The performances of different topologies are evaluated and compared from multiple perspectives. Moreover, the future trend of eliminating the line frequency transformer (LFT) is discussed. This work can provide guidance for future designing and implementing of power-electronics-based P2H systems.

“…Additionally, due to this reason, they are named PWM regenerative rectifiers [330]. These converters are presented in a wide variety of applications, e.g., for power quality mitigation in distributed networks [331], variable speed drives [332], charging stations [333], EV battery chargers with V2G and vehicle-to-home (V2H) modes [334], UPSs [335], and other applications whose bidirectional power flow is the main requirement. Below, power electronics converter topologies used in different common electrical appliances, in order to improve power quality, are presented.…”

Nowadays, new challenges arise relating to the compensation of power quality problems, where the introduction of innovative solutions based on power electronics is of paramount importance. The evolution from conventional electrical power grids to smart grids requires the use of a large number of power electronics converters, indispensable for the integration of key technologies, such as renewable energies, electric mobility and energy storage systems, which adds importance to power quality issues. Addressing these topics, this paper presents an extensive review on power electronics technologies applied to power quality improvement, highlighting, and explaining the main phenomena associated with the occurrence of power quality problems in smart grids, their cause and effects for different activity sectors, and the main power electronics topologies for each technological solution. More specifically, the paper presents a review and classification of the main power quality problems and the respective context with the standards, a review of power quality problems related to the power production from renewables, the contextualization with solid-state transformers, electric mobility and electrical railway systems, a review of power electronics solutions to compensate the main power quality problems, as well as power electronics solutions to guarantee high levels of power quality. Relevant experimental results and exemplificative developed power electronics prototypes are also presented throughout the paper.
