Power electronic technology is a new branch of applied to power field is to use the electronic technology, power electronics device (such as thyristor and GTO, IGBT etc.) to the electric power for transformation and control technology. Power electronic technology "power" which transform the power can be big to hundreds of MW GW even, also can small to several W even under and 1W leds, the information processing as information electronic technology different power electronic technology is mainly used in electric power transformation.
introduction
Power electronic technology into power electronics device manufacturing technology and communication technology (rectifier, inverter, the chopper, frequency conversion, covert, etc.) two branches.
Has become a modern electrical engineering and automation major indispensable specialized fundamental course, a door in cultivating the specialized talented person occupies an important position.
Electric Power Electronics (Power Electronics) this name is in the 1960s appear. In 1974, the United States with a fall W.N ewell (pictured) to power a triangle electronics are described, think it is by the power of science, electronics and control theory formed three course cross. This view is the world generally accepted. "Power electronics" and "power electronic technology" are respectively from the academic and technical engineering 2 different Angle to call.
Generally, the birth of power electronic technology in 1957, the American general electric company developed first thyristor for marks, the power electronic technology concepts and foundation was that the thyristor and brake canal converter technology development and establish. It has been used in power transformation of electronic technology, so thyristor can be called the period before appearance of power electronic technology prehistoric or dawn period. In the late 1970s with the door very can shut off the thyristor
