摘要

48 V输入电压调节模块是一种直流-直流供电电源,主要用于计算机微处理器供电。基于三电平变换器理论,提出了一种交错正激式三电平直流变换器,并使用这种结构设计了输入电压为48 V的电压调节模块。分析了这种变换器的工作过程、三电平工作的环境,并与普通的交错并联型Buck变换器进行比较,构建了一个输出0.8 V/100 A 80 W的模型样机并进行了试验验证。实验表明,这种变换器提高了电压调节模块的动态响应速度,减小了输出滤波电容器的大小,有广泛的应用价值。
        The voltage regulator module( VRM) is a DC to DC power supply,which is mainly used to power for microprocessors. A staggered forward mode three lever DC converter is presented based on the theory of three lever convertor. Compared with an interleaving Buck converter,a 48 V input voltage regulator module is designed based on this new structure,where the working processes of this convertor and the environment of the three level DC are analyzed and simulated. Furthermore,a 0.8 V/100 A 80 W-output prototype is demonstrated and experimented. The experiment results are shown that the respond speed is improved and the output filter capacitor is decreased.
