摘 要: | 为了能够实现交-交变频2个频级之间的平滑过渡,缩短平滑过渡时间,采用了固定点切换与软过渡相结合的方法,在Matlab/Simulink环境下编写S函数实现触发策略和频级切换,并建立了仿真模型,进行了仿真。由仿真结果分析,此法能够有效减小频级切换时对电机的冲击,过渡时间也较为理想。

Smooth Transition Simulation of AC/AC Frequency Converter Based on S-Function |

Abstract: | A method of combining fixed-point switching and soft transition is adopted for achieving smooth transition of AC/AC frequency converter between two frequency levels and shortening the time of smooth transition.In the Matlab/Simulink,S function was written to achieve the trigger strategy and frequency switching and the simulation model was established.Simulation was done and the results prove that the impact of the frequency switching on the motor can be reduced effectively with this method.The transition time is also ideal. |

Keywords: | AC/AC frequency converter S-function smooth transition transition time |
