功率半导体是弱电控制与强电运行之间、信息技术与先进制造之间的桥梁,是国民经济的重要基础,在国民经济各领域和国防工业中无所不在。随着世界各国对节能减排的需求越来越迫切,功率半导体器件已从传统的工业控制和4C(通信、计算机、消费电子、汽车)领域迈向新能源、轨道交通、智能电网、变频家电等诸多产业。 Power semiconductors are a bridge between weak electricity control and high-voltage operation and between information technology and advanced manufacturing. They are an important foundation of the national economy and are ubiquitous in all fields of national economy and national defense industry. As the world’s demand for energy conservation and emission reduction becomes more and more urgent, power semiconductor devices have moved from traditional industrial control and 4C (communications, computer, consumer electronics and automotive) to new energy, rail transit, smart grid, And many other industries.
