Bifurcation Control of Current-type Boost Converter

Due to the high frequency action of the switch, the Boost converter will exhibit bifurcation and chaotic behavior, which is not conducive to the normal operation of the system. In this paper, the bifurcation behavior of Boost converters is analyzed, and based on the idea of feedback, a method of segmented pole configuration is proposed to suppress the bifurcation phenomenon of the converters. First, the mathematical model of the converter is established, and the bifurcation and chaotic behavior of the converter are reproduced. Then, a feedback control method with segmented pole configuration is adopted to keep the system in a single-cycle stable state. The simulation results show that the strategy is simple and convenient to implement, and can effectively suppress the bifurcation phenomenon.
