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.

交错函数降压变换器R^{2}P^{2}$的分析与设计

许多应用使用功率转换应用DC/DC转换器具有宽转换范围和能力，以提供高电流或电压水平。低压应用已标准化为48V, 24V, 12V和5V值，适用于LED照明，电池组和电信系统电源等不同应用。DC/DC变换器必须满足高变换比、高功率密度、高效率、输入输出电流和电压纹波小的要求。本文提出了一种基于R^{2}P^{2}$交错函数的二次降压变换器的分析与设计，用于低电压大电流应用。介绍了变换器在开关切换过程中的工作模式。本文还介绍了平均模型，并与文献中报道的一些拓扑结构进行了比较。
