Analysis and Design of Buck Converter $R^{2}P^{2}$ with Interleaved Function

Abstract

Numerous of applications use power conversion apply DC/DC converters with wide transformation ranges and the capacities to provide high current or voltage levels. Low voltage applications have been standardized to 48V, 24V, 12V and 5V values for different applications such as LED lighting, battery banks and power supplies for telecommunication system. Some requirements that DC/DC converters must meet are high transformation ratios, high power density, high efficiency and low current and voltage ripple at the input and output. In this work, the analysis and design of a Quadratic Buck Converter based on the concept of $R^{2}P^{2}$ with interleaved function is proposed for low voltage and high current applications. The operating modes of the converter during the switching process of the switches are presented. The average models are also presented as well as some comparative aspects with some topologies reported in the literature.
