“…In addition, the SiC device has higher efficiencies for high power switching devices, which can operate at higher temperatures of ~600 °C without much change in their electrical properties compared with the Si devices (~200 °C). The SiC devices are one of the leading candidates of next generation power devices [5][6][7][8][9][10][11].…”

Abstract. Spherical silicon (Si) photovoltaic solar cell systems combined with an electric power inverter using silicon carbide (SiC) field-effect transistor (FET) were constructed and characterized, which were compared with an ordinary Sibased converter. The SiC-FET devices were introduced in the direct current-alternating current (DC-AC) converter, which was connected with the solar panels. The spherical Si solar cells were used as the power sources, and the spherical Si panels are lighter and more flexible compared with the ordinary flat Si solar panels. Conversion efficiencies of the spherical Si solar cells were improved by using the SiC-FET.

“…As a case study, here the focus is on the use of both 650 V and 1200 V rated devices within a 3-level inverter topology, of common use in a range of applications including photo-voltaic, avionics, automotive, industrial. The investigations in [14] have pointed out the superior performance of SiC MOSFETs even as a drop-in replacement of Si, that is with devices using the same commercial type package (TO220 and TO247), in terms of efficiency, switching frequency capability, stability over temperature, circuit complexity and, to some extent, electro-magnetic signature.

Relatively recently, SiC power MOSFETs have transitioned from being a research exercise to becoming an industrial reality. The potential benefits that can be drawn from this technology in the electrical energy conversion domain have been amply discussed and partly demonstrated. Before their widespread use in the field, the transistors need to be thoroughly investigated and later validated for robustness and longer term stability and reliability. This paper proposes a review of commercial SiC power MOSFETs state-of-the-art characteristics and discusses trends and needs for further technology improvements, as well as device design and engineering advancements to meet the increasing demands of power electronics.

“…In [13], the employment of 1200-V SiC JFETs realized a 5000-W three-phase inverter with a high switching frequency of 144 kHz. Recently, [15,16] reported all SiC inverters. Some authors [17][18][19] also gave a comparative study of Si-and SiC-based power converters.…”

This paper reports a 100-W class transportable photovoltaic (PV) power generation system built with SiC power devices. Conventionally, studies on SiC power converters have mostly focused on multi-kW applications. In this paper, we have verified the feasibility of the SiC power devices for sub-kW PV power generation systems. The developed PV power generation system consisted of a spherical Si solar cell module, a 150-W SiC PV-inverter unit with maximum power point tracking (MPPT) function, and a 12-V Li-ion battery. The total weight of the system was just 4.3 kg. Conversion efficiencies of the MPPT charge controller and the direct current-alternating current converter reached 98.0% and 88.4%, respectively. The developed system exhibited stable output power characteristics, even when the weather conditions were fluctuated. These compactness, high efficiencies, and excellent stability clearly indicated the feasibility of SiC power devices even for sub-kW class PV power generation systems. This kind of system would be available for the applications where compactness and transportability are of tremendous importance.
