Abstract :
The aim of this article is to assess the PWM techniques for BLDCM drives. The criteria for assessment include the driver circuit, reversal dc-link current, circulating current of floating phase, and back-EMF detection. The advantages and disadvantages of five PWM techniques for BLDCM drives will be analyzed and confirmed by the experimental results. The results presented in this article are expected to provide a clearer picture of PWM techniques for the applications of BLDCM drives.
