| 摘 要： | 根据多电平Buck型开关变换器工作原理,在低频、小信号、小纹波的假设条件下,利用状态空间平均法和欧拉公式建立了从控制到输出的数学模型,分析可知多电平与二电平Buck型变换器的数学模型具有一致性.设计了补偿网络对系统进行了串联校正,仿真和实验验证了数学模型和控制策略的合理性,为其他多电平开关变换器的分析和设计提供了理论依...

| Abstract: | According to the principle of the multi-level converter,on the premise of low-frequency,small signal and small ripple wave,the small signal math model from the control to output is established by using the state-space av-eraging method and euler formula.Analysis shows multi-level and two-level Buck converter has the consistency of the mathematical model.The compensation network is designed for the series calibration system,simulation and experimen-tal results verify the reasonableness of control strategies.... |
