Abstract

A novel DC-DC step-down converter with interleaved control for low output-voltage and high output-current applications is presented in this paper. The voltage gain of the proposed converter is half of the conventional buck converter with reduced current stresses on power devices and low output-current ripple are reduced. The operating principle, steady-state analysis, and small-signal model analysis are discussed in detailed. Finally, a prototype circuit of the proposed converter with 12-V input voltage, 1.5-V/40-A output is implemented to verify the performance.
