Abstract


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