摘要：
A new two-stage buck topology for voltage regulators (VRs) is proposed in this paper. Continuous input current, intermediate bus current and output current can be achieved without intermediate bus capacitor. Good stability of the cascade converter and better transient response than conventional buck convertercan also be achieved. Detailed theoretical analyses have been presented. A 1V/25A experimental prototype converter based on the proposed two-stage topology has been built up to verify the theoretical analysis. Experimental results meet the theoretical analysis very well.
