摘　　要：提出了统一平移时间常数的方法实现分频下的调压调速。该方法通过对所有晶闸管触发时刻后移实现某分频下输出电压的连续调节,进而实现电机转速的连续调节。最后在MATLAB/SIMULINK下搭建了系统仿真模型并以ARM为主控制器设计了六脉波交-交变频调速系统,对统一平移时间常数分频调压方法在交-交变频闭环调速系统中的应用效果进行了仿真和实验研究。结果证明,该分频调压方法能很好满足交-交变频闭环调速的需求。The voltage regulation method in the divide frequency called unified delay of the triggering time was proposed, which moved all of the thyristor's triggering times back to regulate the output voltage in a certain divided frequency,and hence,the stepless speed regulation can be realized. Finally, the simulation model of the system was built in MATLAB/SIMULINK software, and the six-wave AC-AC frequency conversion system was designed based on ARM controller. The proposed method has been verified by the simulation and experiment results, which show that this method can meet the demand of the closed-loop speed regulation system driven by the AC-AC frequency converter properly.
