摘要
In conventional PWM converters, the dynamic performance is limited by the inductor. Switching capacitor converters utilize the capacitor as the energy transmitter and have good transient response. However, their output voltage cannot be regulated by the duty cycle. To combine the advantages of the above two kinds of converters, this paper proposes a family of switching capacitor regulators which are derived from basic switching capacitor cells and basic regulator cells. Each of the derived converters is the combination of a switching capacitor converter and a PWM converter. And they have the following advantages: 1) fast transient response and 2) the regulated output voltage. A 12 V/16 A isolated converter and a 1.2 V/130 A voltage regulator module prototype were built in the lab to verify the theoretical analysis.
