In accordance with the implementation of duty ratio, 2 制;磁通型控制;V 控制;脉宽调制;脉冲频率调制 there are two basic modulations which are pulse width modulation (PWM) and pulse frequency modulation (PFM). It 0 引言 is proposed that control techniques of switching converters are composed of combining “control” and “modulation”. Operation 从20 世纪60 年代开始,开关变换器的控制技 principles, intrinsic characteristics, inherent relations, 术经历了 50 多年,取得了大量的研究成果,对电 advantages and disadvantage
