... several consecutive torque ripple and distortions of the stator voltage are periods. A filtration of the volatile switching frequency is reduced. difficult, and therefore the level of interference is large. The control structure is shown in Fig. 5. Description of The constant switching frequency can be achieved by the each block is the same ...
