摘要

多相降压由于其成本低、结构简单，在CPU稳压模块(VRM)设计中占有重要地位。但基本的瓶颈是高开关频率下的窄占空比。本文重点研究了全桥变换器与降压变换器并联的仿真，以提高其动态性能。详细讨论了吸引人的控制方法。考虑了A19 V输入，1V/30A输出，300 kHz开关频率，并使用PSIM软件对性能进行了验证。研究结果加强了动力性能的改善。

Dynamic Performance Enhancement of Full Bridge Converter as CPU VR

Multi-phase Buck is prominently used in CPU Voltage Regulator Module(VRM) design as it has low cost and simple structure. But the fundamental bottleneck is narrow duty cycles at higher switching frequencies.This paper highlightsthe simulation of a full bridge converter in parallel with buck converter for enhancing the dynamic performance.Theattractive control approachis discussed in detail. A19 V input, 1V/30A output with 300 kHz switching frequencyisconsidered,and the performanceis instigatedusing PSIM software. The results intensifythe improvement in the dynamic performance.
