These models belong to a class of dynamical systems called Variable Structure Systems (VSS). From a classical design point of view, it is of interest to know the dynamical behavior of the system when some parameters are varied. Usually, Pulse Width Modulation (PWM) is adopted to control a DC\u2013DC converter. When this kind of control is used, the resulting mathematical model is nonautonomous and periodic. In this case, the global Poincar\u00e9 map (stroboscopic map) gives all the information about the system. <\/jats:p><jats:p> The classical design in these electronic circuits is based on a stable periodic orbit which has some desired characteristics. In this paper, the main bifurcations which may undergo this orbit, when the parameters of the circuit change, are described. Moreover, it will be shown that in the three basic power electronic converters Buck, Boost and Buck\u2013Boost, very similar scenarios are obtained. Also, some kinds of secondary bifurcations which are of interest for the global dynamical behavior are presented. From a dynamical systems point of view, VSS analyzed in this work present some kinds of bifurcations which are typical in nonsmooth systems and it is impossible to find them in smooth systems. <\/jats:p>","DOI":"10.1142\/s0218127403006728","type":"journal-article","created":{"date-parts":[[2003,3,18]],"date-time":"2003-03-18T11:24:52Z","timestamp":1047986692000},"page":"427-451","source":"Crossref","is-referenced-by-count":43,"title":["TWO-DIMENSIONAL BIFURCATION DIAGRAMS: BACKGROUND PATTERN OF FUNDAMENTAL DC\u2013DC CONVERTERS WITH PWM CONTROL"],"prefix":"10.1142","volume":"13","author":[{"given":"L.","family":"BENADERO","sequence":"first","affiliation":[{"name":"Departament Fisica Aplicada, UPC, Jordi Girona 1-3, Campus Nord-modul B4, 08034 Barcelona, Spain"}]},{"given":"A.","family":"EL AROUDI","sequence":"additional","affiliation":[{"name":"Departament Fisica Aplicada, UPC, Jordi Girona 1-3, Campus Nord-modul B4, 08034 Barcelona, Spain"}]},{"given":"G.","family":"OLIVAR","sequence":"additional","affiliation":[{"name":"Departament Fisica Aplicada, UPC, Jordi Girona 1-3, Campus Nord-modul B4, 08034 Barcelona, Spain"}]},{"given":"E.","family":"TORIBIO","sequence":"additional","affiliation":[{"name":"Departament Fisica Aplicada, UPC, Jordi Girona 1-3, Campus Nord-modul B4, 08034 Barcelona, Spain"}]},{"given":"E.","family":"G\u00d3MEZ","sequence":"additional","affiliation":[{"name":"Departament Fisica Aplicada, UPC, Jordi Girona 1-3, Campus Nord-modul B4, 08034 Barcelona, Spain"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1109\/63.662832"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1109\/81.847870"},{"key":"rf3","first-page":"687","author":"Benadero L.","journal-title":"Electron.
