摘要
本文研究了空间电压矢量选取的一般方法,提出一种新的研究方法——MMF等效法,这种新的方法能推广到n相电机控制中,它是从电机学的角度进行分析,在电压逆变器控制多相电机过程中,该方法通过电压分频和绕组转换,使转换前后的MMF保持不变,然后将通过逆变器开关组合得到的各个电压值沿各自电压方向合成,通过合成更简洁地得到一组理想的电压矢量,并与一般选取方法采用矢量分解投影得到的结果相吻合。
This paper presents general method of selecting the best SVPWM, and a new research method-MMF（Magnetic Motive Force） equivalent method. The new method can be used for n-phase motor control. In the progress of voltage inverter controling multi-phase motor, the MMF is constantly kept by voltage defrequency and winding switch. Then, each voltages gained from inverter switch are combination composed along with each direction, to gain a set of perfect voltage vector. The results are fit with that of result gained by choosing general method, which using decomposing projection.
