文档介绍：Power electronic technology 1 Profile: Power electronic technology isa new branch applied to power field ,it isa technology which use s the power electronics device (such as thyristor and GTO, IGBT etc.) to transform and control the electric power. The power which transform ed byp ower electronic technology can be big to hundreds of MW even GW, also can be small to several W even under and 1W , the information electronic technology is different from power electronic technology , the power electronic technology is mainly used in electric power electronic technology are put into power electronics device manufacturing technology munication technology two electronic technology has e a indispensable specialized fundamental course in modern electrical engineering and automation major, which playes an important role in cultivating the specialized talented person. Power Electronics this name appears in the 1960s . In1974, ewell from the United States use a fall triangle to described the Power Electronics, and think s it is made of the cross of the power of science, electronics and control theory three courses. This view is generally accepted by the world. "Power electronics" and "power electronic technology" are called respectively from the academic and technical engineering two different a ngle . Generally, the birth of power electronic technolo
