交-直-交变频器 meaning in English

ac-dc-ac frequency converter

The steady state and transient characteristics of the aceg system are simulated , the harmonics of the emf and stator current and rotor current as well as mc ' s input current are researched . the operation characteristics of aceg with mc as an exciter are compared to those of aceg with ac - dc - ac converter and cycloconverter as an exciter . the results in this thesis will be helpful to the design of the aceg excitation control system
利用所建模型，对交流励磁发电机系统的稳态调节特性、暂态特性进行了仿真研究；仿真研究了发电机定、转子电流和感应电势及变频器输入电流波形，并作了相应的谐波分析；与交-直-交变频器和交-交变频器作励磁电源时发电机的运行特性进行了对比分析。
