摘要:
针对光伏发电系统中电流控制型Buck变换器,利用不连续动力学理论分析了其非线性振荡行为. 通过调节控制电路的电压幅值和直流激励电源值,给出碰撞边界的和时钟脉冲触发的参数分岔图,获得了电流控制型Buck变换器从稳定的周期1到混沌状态的参数节点. 分别绘制周期和混沌运动的相轨迹和时序图,分析各子域内具有不同映射结构的系统类型. 研究结果表明,流控制型Buck变换器在参数变化时其运动行为丰富,边界碰撞现象明显,观测到倍周期分岔和阵发混沌. 通过分析映射类型,说明其边界的非线性振荡行为.
Abstract:
Based on the switching boundary of the current controlled Buck converter,its nonlinear oscillation behavior is analyzed using discontinuous dynamics theory. By adjusting the voltage amplitude of the control circuit and the DC excitation power supply value,the parameter bifurcation diagrams of the collision boundary and clock pulse triggering are given,and the parameter nodes of the current controlled Buck converter from stable period 1 to chaotic state are obtained. By drawing phase trajectories and time series diagrams of periodic and chaotic motion,the system types with different mapping structures in each sub domain are analyzed. The research results indicate that the flow controlled Buck converter has rich motion behavior when the parameters change,obvious boundary collision phenomenon,and period doubling bifurcation and Intermittency are observed. By analyzing the mapping type,the nonlinear oscillation behavior of its boundary is explained.
