| 摘 要： | 从非线性动力学的角度研究单端正激变换器并联产生的分叉，讨论了电流环的电流增益Ki1、Ki2，电压环的电压增益Kv1、Kv2对并联电路输出电压的影响，并作了分别以Ki1、Ki2、Kv1、Kv2为参数的输出电压的分岔图．用混沌同步的理论研究了基于Lyapunov函数的混沌同步均流电路的实现，认为这种同步方法具有误差小，电路简单，响应时间快的优点．

| Abstract: | The bifurcation in parallel-controlled forward converters is studied, in the view of nonlinear dynamics. The current gain Ki1, Ki2, the voltage gain Kv1, Kv2 are discussed. Computer simulations are performed to capture effects of variation of some chosen parameters on the system. Current share circuit of chaotic synchronization based on Lyapunov function is researched. This method has advantage of smaller error, simper circuit, quicker response time and so on. |
