| 摘 要： | 在磁通轨迹控制下对三点式逆变器主电路作了理论分析，提出了高频是用外层空间电压矢量与零矢量的切换逼近磁通圆，低频时采用内层空间电压矢量与零矢量的切换逼近磁通圆的控制方法，揭示了空间电压矢量与逆变器输出电压之间存在的关系。推导了带电动机负载时计算负载电流的算式。

| Abstract: | Theoretical analysis is made for the main circuit of 3-level inverter under flux trajectory control.Thecontrol method is proposed that adopts outer space voltage vector at high frequency and inner space voltage vectorat low frequency for switch over with zero vector to approach flux circle,disclosing the relation between space voltage vector and the output voltage of inverter. Arithmetic formula for calculation of loading current with motorload is deduced. |
