| 摘 要： | 单周期控制变换器具有在一个周期内消除输入扰动的优点,在工程中常用小信号模型进行分析和设计.在此首先指出常用小信号模型的不足；其次用Filippov方法得到单周期控制Buck变换器一个完整周期内的状态转移矩阵并对其进行分析.可知当参考电压小于输入电压时,在任何电路参数情况下,单周期控制Buck变换器都处于稳定运行状态.对...

| Abstract: | One-cycle controlled power converter has the ability to reject the input perturbation within one cycle.They are generally analyzed and designed using the small-signal model.The incorrect prediction of these models is pointed out.State transition matrix over a complete clock cycle is derived with Filippov method for one-cycle controlled Buck converters.The results show that one-cycle controlled Buck converter can operate with period-1 under any circuit parameters when the reference is less than the input,and... |
