Perspectives of SiC Power Devices in Highly Efficient Renewable Energy Conversion Systems

Abstract

In the long run, regenerative energy sources represent the most important alternatives to fossil fuels. In general, they are characterized by decentralized logistics and supply capabilities due to ihnerent lower energetic densitiy per are, when compared with the fossil counterparts. As a result, the increased use of regenerative energy sources will require decentralized structures for energy supply, consumption optimisation and regional balancing between supply and demand. Both, the more efficient utilization of fossil energy sources and the utilization of regenerative energy sources, lead to increasingly decentralized supply structures and can be understood as being both complementary and convergent in relation to each other. Most of the converter units for utilization of decentralized energy resources (DER) use power electronics for the AC power conditioning with grid quality. The current paper shows market perspectives of DER applications and the impact of SiC on these application.

Performance evaluation of all SiC power converters for realizing high power density of 50 W/cm³

“…Recently, prototype SiC power modules using SiC-MOSFETs and SiC-SBDs have A part of this work was supported by New Energy and Industrial Technology Development Organization (NEDO) project, Development of Future Power Electronics Technology, Japan. been reported and demonstrated significant power loss reductions compared to conventional Si-IGBT modules [12]- [15]. Therefore, higher power density power converters are expected by using all SiC power modules.…”

4H-SiC Trench Structure Schottky Diodes

“…For example, Power Factor Correction (PFC) is one of the major applications in which a reduction in switching losses provides an increase in operating frequency [1,2]. Renewable energy conversion systems are also promising applications [3]. However applications of SiC Schottky diodes are still limited due to their higher cost than Silicon.…”
