Abstract
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.
