Space vector modulation technique for inverters in the chain with interphase transformers multinu00cdveis

摘要

Space vector modulation technique for inverters in the chain with multinu00cdveis interphase transformers. It is used the concepts of vector representation for the static power converters for implementing a strategy for three-phase current modulation inverters with five levels.It is presented a computational algorithm that provides a modulation with a run mode with operation in order to increase the frequency of operau00e7u00e3o0 of passive elements without increasing the frequency of switching of the switches controlled.Ensures that the average voltage at the terminals of the interphase transformers will be invalid, not causing problems of saturation in magnetic cores. To act in the control of average values of current in the coils of the transformers of interphase, independently and decoupled.
