Abstract

Abstract: In the paper, the stability of Buck-Boost matrix converter in voltage/current control mode is studied, and a nonlinear modeling and analysis method on the Buck-Boost matrix converter is proposed. The discrete iterative nonlinear mapping model of the converter is established. The influence of voltage feedback coefficient K₁ and current proportional coefficient K₂ on system stability is analyzed by sampling the distribution map of output voltage, hence, the stable domain of K₁-K₂ is determined. The influence on converter stability is verified and analyzed by the time domain waveform, the stroboscopic sampling chart and the folded graph, respectively. The effectiveness of the proposed method is further verified by experiments, which is important for the stable operation of Buck-Boost matrix converter.
