摘要
以SPWM-H桥逆变器为研究对象,采用离散映射方法建立该逆变器离散映射模型,研究电路参数与发生混沌现象的关系,直观地展示了逆变器分岔和混沌现象的动态演化过程。仿真研究结果表明该电路中混沌现象确实存在,并且给出了避免系统进入混沌状态的电路稳定运行参数域。
With SPWM-H bridge inverter as the research objective,the discrete reflection method is adopted to establish the discrete reflection model for this inverter in this paper.The relationship between the electric circuit parameters and chaos occurrence is studied,whereby the dynamic evolution process of inverter bifurcation and chaos phenomena can be directly exhibited.The results from the simulation study indicate there exists the chaos in electric circuit and suggests the parameter range for electric circuit stable operation so as to avoid the system entering into chaos state.
