摘要
对基于航空电源的九开关变换器控制方法进行了研究,该系统由永磁同步发电机、九开关变换器以及控制器组成。介绍了九开关变换器的分时控制原理,将变换器的控制分为机侧整流控制模型和网侧逆变控制模型来分别进行研究,机侧与网侧模型都采用了双闭环控制的方法,通过Matlab/Simulink仿真得出:所采用的控制方法达到了变速恒频发电的要求,并有效地减少了网侧输出电流的谐波含量。
The control strategy of nine-switch converter based on aerial electric source was researched on,the system was composed of permanent-magnet synchronous generator,nine-switch converter and controllers. The timesharing control principle of nine-switch converter was introduced,which divided the whole control into rotor-side control and grid-side control,and then reserched on them separately. Both of the rotor-side and the grid-side adopted the method of double-closed-loop control. The system was simulated in Matlab/Simulink and the feasibility of variable-speed constant-frequency generation in this system is proved,as well as the reduction of the harmonic content.
