通信电源及分布式电源主要由前级高频整流器、中间级电池组和后级DC/DC变换器组成。DC/DC变换器的输入部分通常采用大功率Boost变换器，以将前级与中间级的直流电压提升至一定的幅度，从而更方便地形成所需提供给负载的各种电压。Intel CPU广泛用于IT工业，其对电源的要求越来越严格，需要提供更低的电压、更大的电流及更快的动态响应。为了改进Buck类型电压调整模块（Voltage Regulator Module，简称VRM）的动态响应要求，广泛使用多相交错并联技术，以实现快速的动态响应且极大地降低输出电流纹波。文章以一个大功率的四相交错并联Boost变换器作为设计实例，详细说明了其工作原理及主要器件的设计与选用；论证了该项技术用于Boost DC/DC变换器的多种优点，从而证明了多相交错并联技术的先进性和实用性。

Communication power and distributed power mainly from the former level high-frequency rectiifers, battery packs and intermediate level after level DC/DC converter components. DC/DC converter power input section usually Boost converter, before the class and the middle class will be the DC voltage raised to a certain extent, marking it easier to form the desired variety of voltage supplied to the load. Intel CPU are widely used in IT industry, its power requirements become more stringent, the need to provide a lower voltage, higher current and faster dynamic response. In order to improve the dynamic response of Buck type Voltage Regulator Module(VRM)requirements, multiphase interleaving technique widely used in order to achieve fast dynamic response and greatly reduces the output current ripple. In this paper, a high-power four-phase interleaved Boost converter as a design example, a detailed description of its working principle and main components the design and selection;demonstration of the technology used Boost DC/DC converter several advantages. Thus proving the multiphase interleaved advanced technology and practicality.
