摘要
分析了目前有关交流电机软启动技术理论的发展状况,研究了以晶闸管降压调速原理为基础的功率因数闭环控制以及分级变频软启动控制原理和两相变频软启动原理,指出了今后交流电机软启动理论的研究方向。
The paper analyses the state about soft-starting theory of induction motor, and discusses the closed loop control method of displacement angle, which based on regulating speed of thyristor reducing voltage, and soft-starting control theory of discrete frequency, two phase frequency-variable soft-starting control theory. In the end, it points out the direction of soft-starting theory studying about induction motor.
