摘要
根据工程实践需要,针对空间矢量调制(SVM)电流源型变频器平波电抗器的取值问题,提供了一套方便有效的设计方法。笔者从三相电流源型变频器前后级功率管的调制方式出发,通过分析直流电感两端电压的变化,根据直流电流波动要求,得到直流电感的计算公式。最后采用公式得到的电感值,通过仿真初步验证了该设计方法的可行性。
According to needs in engineering practice,for the value of smoothing reactor of current-source converter based on space vector modulation（SVM）,we provide a convenient and effective designing method.Realizing the modulation of three-phase current-source converter front and rear-stage power devices,analyzing direct current inductance voltage,according to fluctuation requirement of direct current,this paper provides the formula to select smoothing reactor.At last,inductance value through the formula is obtained and verified by simulation,and the result confirms the feasibility of the design method.
