摘要
碳化硅电力电子器件具有高压、高温和高效率等优势,是智能电网中理想的电力电子器件。介绍了近年来碳化硅材料及器件在研发和产业化方面的最新发展。随着6英寸碳化硅单晶和外延产品的问世并日趋成熟,更高电压等级、更大导通电流、更高效的碳化硅电力电子器件将被研发出来。并对其在电网中的应用现状与前景进行了展望:碳化硅器件在诸如分布式发电并网装置、电力电子变压器和电力电子断路器等方面显示了巨大的性能优势和市场前景。
Silicon carbide（ SiC） power devices have the advantages of high voltage,high temperature and high frequency,which showgreat potential to be used in future power grid. Several major breakthroughs in RD and industrialization of SiC material and devices obtained resently are introduced. With 6 inch 4H-SiC wafer and its extensional products are avaliable and getting more mature,SiC power devices with higher voltage,larger conduct current and more efficiency will be developed. The perspectives of applications of SiC power electronic devices in power grid are proposed. Full SiC power devices have shown great advantanges and market perspect of distributed energy converter,solid-state transformer and solid-state breaker.
