Power electronic technology is divided into power electronics manufacturing technology and variable flow technology (rectifier, inverter, chopper, inverter, a disguised form, etc.) two branches. Has now become indispensable to modern electrical engineering and automation major a professional basic course, occupies an important position in cultivating the professional talents.

In 1974, the United States W.N ewell with an inverted triangle (pictured) for power electronics are described, that it is by electricity, electronics and control theory of the three disciplines cross. This view is widely accepted around the world. \"Power electronics\" and \"power electronic technology\" is respectively from the Angle of the two different academic and engineering technology to call.

electrical energy is converted into another form of industrial electricity.
