基于Saber的SVPWM逆变器控制仿真

摘要

Taking the rectifier module of high-frequency intelligent switching power as research object, and using passive power factor correction and DC/DC converter to design and improve the principle of rectifier module. After designing and debugging the hardware and circuit of rectifier module, the rectifier module can effectively solve the rectifier problem of high-frequency intelligent switching power supply system. At the same time, the module has the features of the reliability, stability, small size, low noise, energy efficient, easy maintenance and so on, which can satisfy the trend requirements of high-frequency intelligent switching power.%为了对航空航天飞机供电系统的变频系统的逆变部分做仿真,采用了空间矢量PWM(SVPWM)控制策略,使变频后输出的电流在正弦波附近变化.SVPWM是依据变流器空间电压(电流)矢量切换来控制变流器的一种控制策略.在仿真软件Saber环境下运用MAST语言根据SVPWM的控制算法建立了SVPWM的逆变模型的实验,得到了与理论分析符合的仿真实验结果.
