Simplified cascade multiphase DC-DC buck power converter for low voltage large current applications: part I --- steady-state analysis

This paper presents a new simplified cascade multiphase DC-DC buck power converter suitable for low voltage and large current applications. Cascade connection enables very ratio without using small duty cycles nor transformers. Large with ripple content is achieved by the technique. The proposed needs smaller number of components compared to conventional converters. also useful analysis method optimize phase number. Simulation experimental results are included verify basic performance converter.
