摘　　要：为了适应计算机和通信技术的迅速发展,新一代计算机微中央处理器(CPU)的供电电压越来越低、供电电流以及电流变化率越来越高.这就决定了CPU的供电电源——电压调节模块VRM(Voltage Regulator Module)的发展趋势是低电压、大电流输出并且具有良好的动态响应能力.在阐述了近年来VRM拓扑结构的发展概况,包括非隔离型、隔离型以及两级式的拓扑结构后,指出了未来VRM设计中的一些亟待解决的问题.To accommodate the rapid development of the computer and information technology, the new generation of Central Processing Unit＇ s （CPU） power supply voltage trends to be lower, while its current and current slew rate be- come larger. Therefore, as the dedicated power supply of CPU, voltage regulator module （VRM） presents the following developmental trends ： low voltage, large current output and good dynamic characteristics. This paper expounds the development of the topologies of VRM, which consist of the non-isolated, isolated and two-stage topologies. Several critical issues for the future design considerations of VRM are also pointed out in the end.
