摘要
对工作在电感电流连续模式下的 PWM型降压式 DC- DC变换器进行了研究 ,采用连续采样、恒频的 PWM控制环调节 DC- DC变换器的输出电压 .通过理论分析与实验电路两方面证实了DC- DC变换器在某些特定的电路参数下会出现多脉冲、倍周期分叉及混沌等现象 .
A buck DC DC converter operating in continuous conduction mode,whose output voltage is controlled by naturally sampled,constant frequency PWM,is studied.Under certain values of the circuit parameters,instability multiple pulse,double period bifurcation and chaos are proved both theoretically and experimentally.
