Abstract

The purpose of this paper is to present performance characteristics of a quick response digital peak-current-mode 380V dc-dc converter for the green IT system. A proto-type is constructed as the digital control dc-dc converter used in the higher voltage direct current (HVDC) system for the green IT. The proto-type uses the digital peak-current-mode control to show a superior transient response. A dc power supply uses 380V in above HVDC system. The transient response of proto-type is indicated in this paper. As a result, the convergence time and undershoot of output voltage are suppressed to one half and one fourth, respectively.
