This work focuses on improving the closed-loop modulation scheme called Feedback Quantizer, which is applied to a three-phase voltage source inverter. This scheme has the natural behavior of mitigating harmonics at low frequencies, which are detrimental to electrical equipment such as transformers. This modulation scheme also provides good tracking for the voltage reference at the fundamental frequency. On the other hand, the disadvantage of this scheme is that it has a variable switching frequency, creating a harmonic spectrum in frequency dispersion, and it also needs a small sampling time to obtain good results. The proposed scheme to improve the modulation scheme is based on a Discrete Space Vector with virtual vectors to obtain a better approximation of the optimal vectors for use in the algorithm. The proposal improves the conventional scheme at a high sampling time (200 \u03bcs), obtaining a THD less than 2% in the load current, decreases the noise created by the conventional scheme, and provides a fixed switching frequency. Experimental tests demonstrate the correct operation of the proposed scheme.<\/jats:p>","DOI":"10.3390\/s24010287","type":"journal-article","created":{"date-parts":[[2024,1,3]],"date-time":"2024-01-03T05:50:38Z","timestamp":1704261038000},"page":"287","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Improved Feedback Quantizer with Discrete Space Vector"],"prefix":"10.3390","volume":"24","author":[{"given":"Mat\u00edas","family":"Veillon","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Faculty of Engineering, Universidad Cat\u00f3lica de la Sant\u00edsima Concepci\u00f3n, Talca 3467769, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8896-0852","authenticated-orcid":false,"given":"Eduardo","family":"Espinosa","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Faculty of Engineering, Universidad Cat\u00f3lica de la Sant\u00edsima Concepci\u00f3n, Talca 3467769, Chile"},{"name":"Centro de Energ\u00eda, Universidad Cat\u00f3lica de la Sant\u00edsima Concepci\u00f3n, Concepci\u00f3n 4090541, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5390-2855","authenticated-orcid":false,"given":"Pedro","family":"Melin","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Universidad del B\u00edo-B\u00edo, Concepci\u00f3n 4051381, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Galina","family":"Mirzaeva","sequence":"additional","affiliation":[{"name":"School of Engineering, University of Newcastle, Callaghan, NSW 2308, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Rivera","sequence":"additional","affiliation":[{"name":"Power Electronics, Machines and Control Research Group, University of Nottingham, 15 Triumph Rd, Lenton, Nottingham NG7 2GT, UK"},{"name":"Laboratorio de Conversi\u00f3n de Energ\u00eda y Electr\u00f3nica de Potencia (LCEEP), Vicerrector\u00eda de Innovacion, Universidad de Talca, Curic\u00f3 3340000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos R.","family":"Baier","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Faculty of Engineering, University of Talca, Curic\u00f3 3340000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6744-6248","authenticated-orcid":false,"given":"Roberto O.","family":"Ramirez","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Faculty of Engineering, University of Talca, Curic\u00f3 3340000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2048","DOI":"10.1109\/JPROC.2017.2682105","article-title":"Multilevel Converters: Fundamental Circuits and Systems","volume":"105","author":"Akagi","year":"2017","journal-title":"Proc.
