Bifurcation Analysis of Novel Self Operating Flyback Converter

This paper presents the complex behaviour of a novel self-operating flyback converter, which boosts ultra-low voltage. The flyback topology has been selected to study the complex behaviour, which is analyzed from discrete iterative mapping. The input voltage, reference current, and feedback gain parameters are validated to obtain the bifurcations. The transformation of chaotic behaviour from onetime-periodic to two time-periodic of the self-operating flyback converters is observed by varying one parameter while the other parameters are kept constant. The phase plots and respective time-domain currents were also studied. It has been observed from the bifurcation diagram at a particular point, the state of the system proceeds to the nonlinear regime.
