摘要
采用微型计算机控制技术，用单片机对大型同步电动机励磁回路的晶闸管变流装置及其相关的控制电路进行闭环调节和控制，可以完全取代常规的模拟电子控制电路．作为新型的升级换代产品，它具有体积小、可靠性高、调试方便、可拓展性强等优点．
Common simulation electric control circuit can be completely replaced by single-chip computer control circuit. Thyristor transducer and related control circuit in excitation circuit of synchronous motor can be modulated and controlled by using microcomputer control technique. It is considered to be a new small,highly reliable, easily operated, better expanded product.
