Simulation study of bifurcation control in synchronous switching converter

Peak current-mode controlled synchronous switching converter has excellent performance and has a wide range of applications in the industrial sector. The discrete iterative map of peak current-mode controlled synchronous switching boost converter with continuous inductor current mode (CCM) is established in this paper. The bifurcation diagram of the inductor current with the reference current of the feedback loop as the bifurcation parameter, the time-domain waveform, and its phase portrait and the Poincare section are obtained in the synchronous switching Boost converter by numerical simulation. The research results show that the increase in the intensity of the controlled voltage source can change the discharge slope of the inductor current, and thereby affect the bifurcation and chaotic state and the movement of periodic orbits of the system.
