Alternative Feedback Quantizer Using Space Vector Modulation

Feedback Quantizer (FBQ) is a closed-loop modulation scheme with low harmonic content at low frequency and good tracking of the voltage reference at fundamental frequency. A good modulation scheme to be applied in transformer dependent systems that are not saturated by the low frequency harmonic components. This paper presents an alternative for the application of FBQ using Space Vector Modulation, with the objective of obtaining a higher accuracy in tracking the reference and improve the harmonic content of this technique at low sampling times. The simulated results show the fulfillment of the objectives satisfactorily.
