Abstract:
A DC powered computer system comprising:a. a utility power input which supplies AC utility power having a line frequency; b. a line voltage rectifier element which converts said AC utility power to a DC signal; c. an inverter element responsive to said DC signal which establishes an alternating power output; d. a frequency driver which controls said inverter element to establish a distribution frequency; e. a supply transformer element which is responsive to said alternating power output and which establishes at least one distribution output at at least one distribution voltage; f. a power distribution system responsive to said supply transformer element and which provides computer components power at locations electrically remote from said inverter element; g. at least one electrically remote voltage regulation module responsive to said power distribution system comprising; 1) an alternative power input; 2) at least one voltage regulation module transformer which is responsive to said alternative power input; 3) a first switched voltage regulation module rectifier element responsive to said voltage regulation module transformer element; 4) a second switched voltage regulation module rectifier element responsive to said voltage regulation module transformer element; 5) a passive rectifier control to which said first and said second switched voltage regulation module rectifier elements are responsive; 6) a bias input to which said passive rectifier control is responsive; 7) a second harmonics trap which is responsive to said first and said second voltage regulation module rectifier elements; and 8) a substantially non-capacitive DC output system which is responsive to said second harmonics trap; and h. at least one computer component responsive to said DC supply output.
