Research of modeling and simulation to control chaos in H bridge converter

The operation principle of peak current mode control H bridge converter was analyzed. It can observe nonlinear phenomena in H bridge converter after simulating to the model, which builds by the concept of binary logic variables using Matlab/Simulink. According to the characteristics of H bridge converter, a time-delayed feedback control method was applied to suppress the chaos behavior of H bridge converter and make the system changing from chaos to stable cycle. It proved from multi-angle that the control method can broaden the stability scope of H bridge converter by anglicizing the bifurcation point impart to parameters I_ref, E, L and impart of feedback gain k to H-bridge converter stability. Practice proved that the speed of simulation is fast and easy to do theoretical analysis in this method of modeling. The control method can suppress chaos with high efficiency and it can provide theoretical basis for stability design of H bridge converter.
