三相AC/DC软开关变流器的最优矢量控制(英文)

Optimum vector sequence for 3-phase AC/DC soft-switch converter control

分析了矢量控制在三相变流器的应用 ,比较矢量圆的 3种合成方式 ,得出了矢量控制的优化发波方式。考虑了开关信号中的谐振区间 。

This paper analysis the application of vector width pulse modulation in the parallel resonant DC link circuit control. Comparing three different synthesis methods of the vector circle, we have derived the optimum vector sequence for controlling the 3 phase AC/DC soft switch converter, considering the resonant region in the switch signal to reduce the influence of resonance to the lose of effective switch signal ratio.
