Application of SVM Based on Differential Equations in APF;

In this paper,the principle of direct torque control(DTC)for permanent magnet synchronous motor and the effect of voltage vectors on flux linkage and torque are studied,and a new direct torque control with space vector modulation(SVM)is proposed.

In order to solve the problem of direct torque control(DTC)for permanent magnet synchronous motor(PMSM)related to the flux and the torque ripple and the uncertainty of switching frequency,a method which shorten the voltage-vector-function-time by SVM(space vector modulation)is developed,and in order to improve the system performance,the stator flux linkage sectors and vectors are subdivided.

The relationship between space-vector modulation (SVM) and carrier-based modulation for multilevel inverters is still unexplored.

Comparing with normal space-vector modulation (SVM) scheme, the novel space-ve ctor modulation (NSVM) discussed in this paper can reduce the average switching frequency greatly, so that the switching loss can also be reduced.
