Abstract

Wide bandgap (WBG) power electronics is a very small segment of power electronics market (1%) and about 0.05% of the total semiconductor market today. The U.S. has a strong foothold in both the silicon carbide (SiC) and gallium nitride (GaN) markets today, but there exists an increasing competition from Europe, Japan, and China. This work presents market, value chain and energy savings potential analyses for several major application areas: data centers (uninterruptable power supplies (UPS) and server power supply units (PSU), renewable power generation (Photovoltaic (PV)-solar and wind), motor drives, rail traction, and hybrid/electric vehicles. These application areas hold great opportunities for WBG, stemming from increased government efficiency standards and promoting of alternative energy generation and an existing strong supply chain. Major threats to U.S. WBG integration stem from the loss of government assistance, alternative energy saving technologies, and an increasing threat of foreign manufacturers.
宽带隙半导体在电力电子领域的机会
宽带隙(WBG)电力电子是一个非常小的部分电力电子市场(1%)和约0.05%的总半导体市场今天。如今,美国在碳化硅(SiC)和氮化镓(GaN)市场上都有强大的立足点,但来自欧洲、日本和中国的竞争日益激烈。这项工作介绍了几个主要应用领域的市场,价值链和节能潜力分析:数据中心(不间断电源(UPS)和服务器电源单元(PSU),可再生能源发电(光伏(PV)-太阳能和风能),电机驱动,轨道牵引和混合动力/电动汽车。这些应用领域为世界银行集团带来了巨大的机遇,源于政府效率标准的提高、替代能源发电的推广以及现有的强大供应链。美国融入世界银行集团的主要威胁来自政府援助的丧失、可替代的节能技术以及外国制造商日益增长的威胁。
