However, their deduction approaches are not entirely equivalent since they incorporate different averaging processes, thus yielding different small signal transfer functions even under identical operating conditions. Some research studies claimed that the improved SSA can obtain the highest accuracy among all the modeling methods, but this paper discovers and clearly verifies that this is not the case. In this paper, we first review and study these two modeling methods for various DC-DC converters operating in the discontinuous conduction mode (DCM). We also streamline the general model-deriving processes for DC-DC converters, and test and compare the accuracy of these two methods under various conditions. Finally, we provide a selection strategy for a high-accuracy modeling method for different DC-DC converters operating in DCM and verified by simulations, which revealed necessary and beneficial for designing a more accurate DCM closed-loop controller for DC-DC converters, thus achieving better stability and transient response.<\/jats:p>","DOI":"10.1155\/2018\/3901693","type":"journal-article","created":{"date-parts":[[2018,10,28]],"date-time":"2018-10-28T19:30:46Z","timestamp":1540755046000},"page":"1-16","source":"Crossref","is-referenced-by-count":7,"title":["Review and Selection Strategy for High-Accuracy Modeling of PWM Converters in DCM"],"prefix":"10.1155","volume":"2018","author":[{"given":"Yu-Jun","family":"Mao","sequence":"first","affiliation":[{"name":"State Key Laboratory of Analog and Mixed-Signal VLSI, University of Macau, Macau 999078, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3669-6743","authenticated-orcid":true,"given":"Chi-Seng","family":"Lam","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Analog and Mixed-Signal VLSI, University of Macau, Macau 999078, China"}]},{"given":"Sai-Weng","family":"Sin","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Analog and Mixed-Signal VLSI, University of Macau, Macau 999078, China"},{"name":"Department of Electrical and Computer Engineering, Faculty of Science and Technology, University of Macau, Macau 999078, China"}]},{"given":"Man-Chung","family":"Wong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Analog and Mixed-Signal VLSI, University of Macau, Macau 999078, China"},{"name":"Department of Electrical and Computer Engineering, Faculty of Science and Technology, University of Macau, Macau 999078, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2821-648X","authenticated-orcid":true,"given":"Rui Paulo","family":"Martins","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Analog and Mixed-Signal VLSI, University of Macau, Macau 999078, China"},{"name":"Department of Electrical and Computer Engineering, Faculty of Science and Technology, University of Macau, Macau 999078, China"},{"name":"On Leave from Instituto Superior T\u00e9cnico, Universidade de Lisboa, Lisbon 1649-004, Portugal"}]}],"member":"311","reference":[{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/63.85890"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/tii.2012.2220372"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/7.106127"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/63.931052"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/tii.2013.2277942"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/tii.2013.2245140"},{"key":"10","year":"2008"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/tii.2012.2235845"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1049\/el.2015.2241"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/tie.2014.2304911"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/tpel.2006.876848"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/tpel.2014.2322259"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/tpel.2012.2224889"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/63.471285"},{"key":"20","year":"2008"},{"key":"21","year":"2001"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1109\/tpel.2008.2009178"}],"container-title":["Journal of Electrical and Computer Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2018\/3901693.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2018\/3901693.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2018\/3901693.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,10,28]],"date-time":"2018-10-28T19:30:48Z","timestamp":1540755048000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/jece\/2018\/3901693\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,28]]},"references-count":17,"alternative-id":["3901693","3901693"],"URL":"https:\/\/doi.org\/10.1155\/2018\/3901693","relation":{},"ISSN":["2090-0147","2090-0155"],"issn-type":[{"value":"2090-0147","type":"print"},{"value":"2090-0155","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,10,28]]}}}
