�� ��The circuit structure of interleaved flyback converter and its
working principle based on, in order to study the effect of period doubling
bifurcation phenomena on the performance of the system, the
establishment of discrete iterative map equation with discrete time
mapping method, using the bifurcation graph was used to describe the
phenomenon of period doubling bifurcation of interleaved flyback
converter, and compared with the single end flyback converter period
doubling bifurcation. The simulation results show that:in the case of same
parameters, compared with the single end flyback converter, interleaved
flyback converter in E input voltage changes, the stability region is wider,
more easy to control; the other parameters unchanged, change the
capacitance of C, when C=30 μF, the bifurcation point shift left, stability
localized narrowing, and tends to be chaotic.%�������������
