The system is described using a state-space model. Theoretical and simulation studies show that the zero hysteresis control leads to an equilibrium point with the implication of an infinite commutation frequency, while the use of a constant hysteresis band induces a limit cycle with a finite switching frequency. There exists a tradeoff between voltage output ripple and transistor switching frequency. An experimental prototype for the Buck power converter is built, and theoretical results are verified experimentally. In general terms, the Buck converter with the hysteresis control shows a robust control with respect to load variations, with undesired high switching frequency taking place for a very narrow hysteresis band, which is solved by tuning the hysteresis band properly.<\/jats:p>","DOI":"10.3390\/computation9100112","type":"journal-article","created":{"date-parts":[[2021,10,20]],"date-time":"2021-10-20T01:23:46Z","timestamp":1634693026000},"page":"112","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Nonlinear Dynamics and Performance Analysis of a Buck Converter with Hysteresis Control"],"prefix":"10.3390","volume":"9","author":[{"given":"Carlos I.","family":"Hoyos Velasco","sequence":"first","affiliation":[{"name":"Istituto Motori IM, Italian National Research Council, Via Guglielmo Marconi, 4, 80125 Napoli, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8766-5192","authenticated-orcid":false,"given":"Fredy Edimer","family":"Hoyos Velasco","sequence":"additional","affiliation":[{"name":"Department of Electrical Energy and Automation, Faculty of Mines, Universidad Nacional de Colombia, Sede Medell\u00edn, Carrera 80 No. 65-223, Robledo, Medell\u00edn 050041, Colombia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9784-9494","authenticated-orcid":false,"given":"John E.","family":"Candelo-Becerra","sequence":"additional","affiliation":[{"name":"Department of Electrical Energy and Automation, Faculty of Mines, Universidad Nacional de Colombia, Sede Medell\u00edn, Carrera 80 No. 65-223, Robledo, Medell\u00edn 050041, Colombia"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"302","DOI":"10.1109\/JETCAS.2015.2462013","article-title":"A Review on Stability Analysis Methods for Switching Mode Power Converters","volume":"5","author":"Giaouris","year":"2015","journal-title":"IEEE J.
