“…These impressively high stability characteristics, alongside the wide breakdown fields and very low ON-state resistances (it is reported that the R DS(ON) could be as low as 20 times that of silicon devices) of the devices made from wide band gap semiconductors makes this technology very promising and hence the potential future of power electronics [69]. In addition to these advantages, wide band gap (WBG) devices are capable of operating at high frequencies thus having the potential to require much lower filter sizes when they are utilized in converter circuits [70][71][72][73][74][75][76][77][78][79][80]. The efficiency and power density of the converter circuits is also positively impacted when WBG switches are used.…”

As the need for green and effective utilization of energy continues to grow, the advancements in the energy and power electronics industry are constantly driven by this need, as both industries are intertwined for obvious reasons. The developments in the power electronics industry has over the years hinged on the progress of the semiconductor device industry. The semiconductor device industry could be said to be on the edge of a turn into a new era, a paradigm shift from the conventional silicon devices to the wide band gap semiconductor technologies. While a lot of work is being done in research and manufacturing sectors, it is important to look back at the past, evaluate the current progress and look at the prospects of the future of this industry. This paper is unique at this time because it seeks to give a good summary of the past, the state-of-the-art, and highlight the opportunities for future improvements. A more or less ‘forgotten’ power electronic switch, the four-quadrant switch, is highlighted as an opportunity waiting to be exploited as this switch presents a potential for achieving an ideal switch. Figures of merit for comparing semiconductor materials and devices are also presented in this review.
