| 摘 要： | 为了证明SVPWM(空间矢量脉冲宽度调制)原理不仅能用在民用上,也能用于400Hz的航空电源上.仿真中,在建立三相电压型整流器(VSR)数学模型的基础上,将双闭环工程设计方法应用于PWM整流器,通过直接电流控制方法分别进行有功、无功电流的跟踪控制,从而实现了单位功率因数整流.最后给出了在飞机电气系统的条件下,结合三相电雎型整流器的仿真实验结果,仿真结果证明了理论分析,说明了建立的变换器模型是正确的.从而为SVPWM技术在航空电源领域的实际应用及研究提供了一定的参考价值.

| Abstract: | The aim of the paper is to prove that the principle of SVPWM(Space-vector pulse width modulation)can not only be used in civilian area,but also in aviation power system.In simulation,based on the mathematical model of 3-phase voltage source rectifier(VSR),a dual-close-loop engineering design method is applied in the PWM rectifier,combined with the direct current control method to trace active current and reactive current signal,which can realize unity power factor.At the end,the result of simulation in airc... |
