By means of cycle-by-cycle simulations, the evolutionary trend of bifurcation behaviors is identified. The inherent mechanisms of two types of bidirectional Hopf bifurcations are uncovered based on the proposed averaged model. Moreover, stability boundaries in the parameter space are derived with the help of eigenvalue analysis to optimize the circuit design. Furthermore, some important indices with respect to coupling effects are evaluated to assess the coupling effects in the system. Finally, PSpice circuit experiments are performed to verify the bifurcation analysis. <\/jats:p>","DOI":"10.1142\/s021812741950192x","type":"journal-article","created":{"date-parts":[[2019,12,26]],"date-time":"2019-12-26T04:36:48Z","timestamp":1577335008000},"page":"1950192","source":"Crossref","is-referenced-by-count":18,"title":["Stability and Evolutionary Trend of Hopf Bifurcations in Double-Input SEPIC DC\u2013DC Converters"],"prefix":"10.1142","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9960-4311","authenticated-orcid":false,"given":"Hao","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Lab of Electrical Insulation and Power Equipment, School of Electrical Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, P.
