摘要
为了掌握交流变频技术及其应用,针对交交(ACAC)变频和交直交(ACDCAC)变频器技术,从这两种变频电路原理出发,采用SIMULINK工具箱对一种ACAC和一种ACDCAC变频电路进行研究。采用模拟仿真方法对变频调速系统进行分析,设计了ACAC和ACDCAC变频器的SIMULINK模型并进行仿真。通过分析仿真结果展现了交交变频和交直交变频具有的相同和不同点。这种仿真分析方法是学习和理解交流变频技术更有效途径,也是验证变频系统可行性的有效措施。
In order to learn about frequency conversion and its application, a typical AC-AC and an AC-DC-AC frequency converter with pulse width modulation （PWM） are simulated by SIMULINK toolbox, based on principle of AC-AC and AC-DC-AC frequency conversion. And the frequency conversion systems are analyzed in analog method. The modules are designed by SIMULINK toolbox. The end of simulations shows that there are some differ- ence and some common points between AC-AC converter and AC-DC-AC converter. The simulation offers a well method to learn and understand AC frequency conversion converter, and it＇ s also a good way to test and verify fre- quency system.
