摘要
简要介绍电压空间矢量控制原理,用几何作圆法获得逼近园形的磁链轨迹,由磁莲轨迹导出周期开关状态表,采用GAL可编程器件存贮开关状态表并形成PWM信号。给出波形发生器的原理电路,并对此方案的逆变器输出电压作了谐波计算。在稀土永磁同步电动机变频调速系统中应用,效果良好。
The principle of voltage space vector control is explained. The period switch state table is infered from flux linkage locus which approaches to circle and can be obtained through geometrical drawing. In order to store switch state table and to produce PWM signal, programmable GAL is Used. The prirciple circuit of this wavefotm generator and the harmonic calculation of the inverter output voltage of this scheme is also presented. The effect is satisfactory while it is used in the rare-earth PMSM VF SR system.
