摘要
本文以闭环PWM控制的Buck开关变换器为例,采用非线性迭代映射法对其电感电流连续模式工作下,变换器中出现的混沌现象进行了分析研究,并采用PSPICE进行了计算机仿真验证,从而通过理论和仿真证明了在某些电路参数下系统里会出现多脉冲、倍周期等混沌现象。
On the basis of Iterated Nonlinear Mappings, chaos in PWM Buck switching converter operating in continuous conduction is investigated, and it is verified by PSPICE simulation. It is shown under certain parameters chaos will occur.
