摘　　要：以6kV级联型载波移相高压变频器作为研究对象,介绍了其结构与工作原理,进行了仿真试验研究,证明了此种变频器的优越性能。在此基础上,采用恒压频比的控制方法,对6kV高压变频调速系统进行控制。仿真试验结果表明,文中所用控制策略效果优良,完全可以在工业控制中应用。In this paper, the structure and the operational principle of cascaded high voltage inverter based on different carrier phase-shifted angle are first introduced. Simulations on the inverter verified its superiority. Based on this, the constant U/F control method is applied to the 6 kV high-voltage and variable frequency speed-regulating system. The simulation results show that the control strategy in this paper performs well and can be used in industrial control.
