Via cycle-by-cycle computer simulation and experimental measurement of current-mode controlled buck converter with CCL, it is found that a unique fast-slow scale instability exists in the second-order switching converter. It is also found that a unique period-doubling accompanied by Neimark\u2013Sacker bifurcation exists in this simple second-order converter, which is different from period-doubling or Neimark\u2013Sacker bifurcations reported previously. Based on a nonlinear discrete-time model and the corresponding Jacobian, the effects of CCL and input voltage on the dynamics of current-mode controlled buck converter are investigated and verified theoretically. Fixed point analysis for slow-scale low-frequency oscillation is also given to verify the dynamics and the coexisting fast-slow scale instability. <\/jats:p>","DOI":"10.1142\/s0218127413500624","type":"journal-article","created":{"date-parts":[[2013,5,15]],"date-time":"2013-05-15T03:19:19Z","timestamp":1368587959000},"page":"1350062","source":"Crossref","is-referenced-by-count":23,"title":["COMPLEX DYNAMICS AND FAST-SLOW SCALE INSTABILITY IN CURRENT-MODE CONTROLLED BUCK CONVERTER WITH CONSTANT CURRENT LOAD"],"prefix":"10.1142","volume":"23","author":[{"given":"GUOHUA","family":"ZHOU","sequence":"first","affiliation":[{"name":"School of Electrical Engineering, Southwest Jiaotong University, Chengdu 610031, P.
