| Abstract: | This paper studied a DC distributed power system designed for high-performance computers, analyzed the mechanism of power-bus current oscillations resulted from the input ripple current of DC-DC converters, and thereby emphasized the importance of power supply decoupling in large DC distributed power system. This paper discussed the mechanism and the methods of power-bus decoupling in DC distributed power system, and derived formulae for calculating input decoupling capacitance of the DC-DC converters. |
