摘要
运用电路分析理论,根据KVL和KCL定理及其理想运算放大器的特点,对并联DC-DCbuck变换器建立了一个8维分段光滑的状态方程组,文中给出了详细的状态方程推导过程.然后对所建立的动力学模型的非线性动力学性质进行了初步研究,发现在一定参数和外部激励条件下,该系统出现超混沌运动.
In this paper,an eight-orders piecewise smooth state equations for paralleled DC-DC buck converter is setup,by using the KVL theorem,KCL theorem and the characteristics of ideal amplifiers in circuit analysis theories.The process of derivation is presented in detail.Then,the nonlinear dynamics properties of this modeling is investigated preliminarily.The research results show that with some parameters and outside force,this circuit system appears hyperchaos.
