This disruptive change also requires that the modeling, characterization, and testing of those devices must be improved. Therefore, this study focuses on a smart approach developed by the authors in a previous study to estimate the output of low-power voltage transformers (LPVT). The approach\u2014which is based on a sort of modeling in the frequency domain (the so-called sinc-response)\u2014allows obtaining the behavior of the LPVT at rated and distorted conditions. Experimental tests performed on off-the-shelf devices confirm the applicability and effectiveness of the proposed approach when estimating the output response of LPVTs.<\/jats:p>","DOI":"10.3390\/s20174889","type":"journal-article","created":{"date-parts":[[2020,8,30]],"date-time":"2020-08-30T06:06:22Z","timestamp":1598767582000},"page":"4889","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Low-Power Voltage Transformer Smart Frequency Modeling and Output Prediction up to 2.5 kHz, Using Sinc-Response Approach"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3129-7367","authenticated-orcid":false,"given":"Abbas","family":"Ghaderi","sequence":"first","affiliation":[{"name":"Department of Electrical, Electronic and Information Engineering\u2013Guglielmo Marconi, Alma Mater Studiorum\u2013University of Bologna, Viale del Risorgimento 2, 40136 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1739-1277","authenticated-orcid":false,"given":"Alessandro","family":"Mingotti","sequence":"additional","affiliation":[{"name":"Department of Electrical, Electronic and Information Engineering\u2013Guglielmo Marconi, Alma Mater Studiorum\u2013University of Bologna, Viale del Risorgimento 2, 40136 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lorenzo","family":"Peretto","sequence":"additional","affiliation":[{"name":"Department of Electrical, Electronic and Information Engineering\u2013Guglielmo Marconi, Alma Mater Studiorum\u2013University of Bologna, Viale del Risorgimento 2, 40136 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5377-2421","authenticated-orcid":false,"given":"Roberto","family":"Tinarelli","sequence":"additional","affiliation":[{"name":"Department of Electrical, Electronic and Information Engineering\u2013Guglielmo Marconi, Alma Mater Studiorum\u2013University of Bologna, Viale del Risorgimento 2, 40136 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Crotti, G., Gallo, D., Giordano, D., Landi, C., and Luiso, M.
