The author puts forward the thought of analyzing bifurcation and chaos in dc / dc converters with the theories of nonlinear dynamics , and the thought of controlling nonlinear problems with linear controlling methods of modern control theory . chapter three ( research on bifurcation and chaos in pwm dc / dc converters ) first theoretically analyzes and emulates period - doubling bifurcation of pwm dc / dc converters with the " inverse " piecewise numerical emulation . then the author analyzes in detail the sampled - data model , the mathematical model , which is suitable to the nonlinear research of dc / dc converters
第三章( pwm型dc dc变换器中分岔与混沌的研究)首先采用“逆向”分段数值仿真法对pwm型dc dc变换器中的倍周期分岔进行了理论分析与数值仿真；接着详细地分析了适合于dc dc变换器非线性研究的数学模型一采样数据模型，提出了dc dc变换器中存在环面分岔与鞍结分岔的可能性；最后通过电路实验验证了在电路参数发生变化时， dc dc变换器经历一系列的倍周期分岔通向混沌的演化过程，并对混沌态下dc dc变换器的输出特性进行了分析与小结。
