摘　　要：为了达到三相变流器快速性和稳定性的要求,提出了一种电感电压矢量控制方法。根据误差电流的大小分两种情况计算电感电压矢量,再通过空间矢量模型得到交流侧给定输出电压矢量,并运用空间矢量调制来产生六路开关信号,使交流侧电流时刻朝着正确的方向变化,进而消除电流误差。最后通过仿真和实验验证了其动态性能和稳态性能,并充分说明了其可行性和有效性。In order to achieve rapidity and stability requirements for three phase converter, this paper presents an inductance voltage vector control method. Two cases are used respectively by the size of the error current to calculate the reference inductance voltage vector. Then with space vector model the AC side given output voltage vector is obtained, and with space vector modulation six driving signals are generated. Target is to make current change to the right direction, thus the current error can be eliminated. Finally, simulation and experimental are carried out to verify the dynamic and steady-state performance respectively. The feasibility and effectiveness are also be fully demonstrated.
