摘要
晶闸管是一个较理想的无触点开关 ,具有正向压降小 ,关断时间短和体积小等优点 ,这就使它所组成的静止变频电路 ,逐渐取代了旧的变频机组。
Thyristor is an ideal contactless shutter with the advantages of forward voltage minor and reducing turn-off shorter time ,small volume that make statice variable-frequency electric circuit take the place of the old high-frequency aggregates at present, the equipement has been used widely.
