Pages: 107-113
Year: Issue:  9
Journal: Transactions of China Electrotechnical Society

Abstract: 提出了一种新型的开关DC/DC变换器控制方法--多级脉冲调节(MPA)控制方法.MPA控制器在每个开关周期起始时刻根据变换器的输出电压误差,在强弱等级不同的多级脉冲中选取一个作为该周期的有效控制信号.文中分析和讨论了MPA控制原理,研究了工作于电流断续模式的MPA控制Buck变换器的工作过程和小信号模型.分析结果表明,MPA控制具有优异的鲁棒性、瞬态特性和稳态特性.仿真和实验结果验证了理论分析的正...
