THE WATER-COOLED HEAVY-CURRENT POWER SUPPLY UNITS

摘要

The heavy-current power supply units with 400A and 800A load currents and 2V and 5V output voltages are designed. The general power consumption of the computer is 100 KW. Both in computer assemblies and in power supply units the water cooling is used.rnDuring the computer power supply system development the following principal problems are solved:rnthe minimal power supply component and assembly losses provision the efficiency to increase;rnthe heating elements intensive cooling;rnthe power-supply units parallel operation the "hot" redundancy inclu-ding.the power system reliability to raise.
