“…In case of long-haul transmission, HVDC is used and there is opportunity to design and fabricate high voltage solid state silicon carbide converters. The use of larger silicon carbide wafers and the use of single wafer manufacturing has the potential of bringing cost of SiC power electronics at par or lower than silicon power electronics [95]. Based on the isolation techniques it is far more viable to isolate a DC charging station in case of a cyber-attack.…”

“…If the DC power generated by PV and battery-based power network can be used locally, there is no need of transmission of power. This concept is exactly what Thomas Edison proposed and involve minimum distance between power source and load as well as minimum power conversions [95]. In case of long-haul transmission, HVDC is used and there is opportunity to design and fabricate high voltage solid state silicon carbide converters.…”

The expansion of electric vehicles made the expansion of charging infrastructure rudimentary to keep up with this developing technology that helps people in a myriad of ways. The main drawback in electric vehicle charging, however, is the time consumed to charge a vehicle. The fast charging of electric vehicles solves this problem thus making it a lucrative technology for consumers. However, the fast charging technology is not without its limitations. In this paper we have identified the technology gaps in EV fast charging stations mostly focused on the extremely fast charging topology. It will help pave a path for researchers to direct their effort in a consolidated manner to contribute to the fast charging infrastructure. A thorough review of all aspects and limitations of existing extremely fast charging (XFC) stations have been identified and supporting data are provided. The importance of DC power network based on free fuel energy sources and silicon carbide-based power electronics are proposed to provide ultra-low cost and ultra-high speed XFC stations.

“…No supplychain issues in the manufacturing of its related power electronics are predicted due to the abundance of elements of SiC. Higher performance, higher reliability, higher yield, and lower cost of ownership of SiC based power electronics will be provided if policies in favor of electrification of transportation, volume manufacturing, single wafer processing [40] and large diameter wafer manufacturing are implemented [41]. Silicon carbide fabs are migrating from 150 mm wafers to 200 mm wafers [42].…”

Existing extremely fast charging (XFC) of electrical vehicles (EVs) is based on silicon power electronics and internal conversion of AC power into DC power. In this paper it has been shown that silicon carbide power electronics and the use of DC power source in the design of XFC of EVs has many distinct advantages over current XFC of EVs. Silicon carbide power electronics provide reduction of charging time, higher power conversion efficiency, size reduction of heat sink and improved battery's state of health. The use of larger size silicon carbide wafers will further reduce the cost of power electronics based on silicon carbide. Use of green energy sources (solar and wind) and lithiumion batteries for electrical power storage can provide end to end DC power network. Such networks combined with silicon carbide based XFC of EVs can play a revolutionary role in saving green electrical and provide reduced of charging of EVs. This paper reports almost 50% reduction in power losses by using Silicon Carbide DC technology. End to end DC power networks combined with SiC based XFC of EVs can play a revolutionary role in solving climate emergency.

“…The SST is different from the legacy distribution transformers because of the involvement of power electronic converters, which offers typical functionalities, such as multilevel power conversions (high voltage AC/DC power conversion for DC buses, DC/DC conversion for high-frequency DC regulated buses, and DC/AC conversion stages for low-voltage regulated AC buses), and makes it a three-level power exchange [42]. The size of the SST transformer is reduced considerably compared with that of the conventional transformer because of the employment of high-frequency silicon carbide (SiC) insulated gate bipolar transistor (IGBT) technology, which makes it lighter and more compact [43,44]. SST will act as a smart and intelligent plug-and-play interface device that supports different interfaces (AC/DC) via AC and DC ports.…”

Energy Internet is a concept proposed to harness, control, and manage energy resources effectively, with the help of information and communication technology. It improves a reliability of the system, and provides an increased utilization of energy resources by integrating the smart grid with the Internet. A scalable and reliable information and communication architecture is a crucial factor for both the operation and management of the energy Internet. The routing or managing of electrical energy is performed through an energy router (ER), synonymous with a communication router, which routes data packets instead of energy packets. In this paper, a holistic review of the energy Internet evolution in terms of the architecture, types of ERs, and the benefits and challenges of its implementation is presented. An exhaustive summary of the designs and architectures of the different types of ERs is also presented in this paper. The benefits of the energy Internet, along with the challenges of its implementation on a large-scale distributed architecture with the inclusion of renewable energy resources, is discussed. Finally, future prospects for the energy Internet for achieving guaranteed reliability and security is presented.
