Abstract :
Heavy-current power supply units with 400 A and 800 A load currents and 2 V and 5 V output voltages are presented. The general power consumption of a computer is 100 kW. Both in computer assemblies and in power supply units, water cooling is used. During computer power supply development, the following principal problems are solved: minimal power supply components and assembly losses for optimal efficiency; intensive heating elements cooling; power supply unit parallel operation; and the use of “hot” redundancy to improve power supply reliability
