Optimized space vector modulation and regular-sampled PWM: a reexamination

The relationship between space vector modulation and regular-sampled PWM techniques for hard-switching PWM inverters and rectifiers are reexamined in this paper. Space vector modulation with optimized apportioning of null vector time that results in minimum current THD is investigated and is compared with previously known methods. The conventional optimal regular-sampled PWM method and its relation to the optimized space vector modulation are discussed. Optimal discontinuous modulation for minimizing both the switching losses and the current THD is also studied.
