外文翻译--电力电子技术
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 WN 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 GTO a bipolar transistor Power BJT Power MOSFET Power - MOSFET as a representat
