Abstract :
When the Boost converter is in the chaotic state, it does not work well. In order to suppress chaotic phenomena in the Boost converter, a parameter adjustment method is proposed, by establishing the mathematical model and analyzing the bifurcation diagram, the Poincare section, the phase portrait, the output voltage waveform and the inductor current waveform. Without determining target orbits, only by adjusting an external parameter, the parameter adjustment method can stabilize the chaotic Boost converter to the period-2, period-8, period-10, period-14 orbits.
