| 摘 要： | 在供电电源为带谐波的整流源而非理想直流电源的情况下,研究了电流模式控制Buck变换器的分岔和混沌现象.首先给出Buck变换器在连续导通模式下的数学模型,然后对理想直流电源供电和3种模拟的含不同电压幅值谐波分量的整流源供电的情况,在改变电压平均值的情况下,通过计算机仿真得到不同的分岔和混沌现象,并进行比较分析,最后给出典型的含10%直流电压幅值谐波的纹波电压对应的电流和电压波形图,并进行比较分析.

| Abstract: | The bifurcation and chaos phenomena in a current mode controlled buck converter were explored,with the rectified output voltage as the input of the converter instead of a regulated ideal DC power supply.The mathematical model was developed under the continuous conduction mode.Considering the average value of DC input voltage as a variable,a set of bifurcation and chaos diagrams were given through computer simulation,when the converter is eguipped with regulated DC power supply and three rectified DC sources with different ripple content.The diagrams about inductive current and capacitor voltage were given and analyzed when the input comes from a rectified DC source with 10% ripple content. |
