Abstract：In order to analyze the influences of digital controller parameters and main circuit parameters on H-bridge inverter performance,By using chaotic dynamics theory,based on the circuit principle analysis,the discrete mathematical model was established by stroboscopic map method.The effect of control parameters on system performance was researched by combining bifurcation diagram with fold figure and Lyapunov exponent method,and the results were verified by time-domain waveform.Finally,the nonlinear behaviors under different main circuit parameters were studied by bifurcation diagram.The results showed that the system could run in a single cycle state,multiple periodic bifurcation state or chaos state stability under different control parameters and circuit parameters,and had typical nonlinear behaviors.The research results provide a certain guidance for controller design and circuit parameters setting of H-bridge inverter.
