VORRICHTUNG FÜR EINE SYMMETRISCHE DREIPHASIGE WECHSELSTROM-LEISTUNGSVERSORGUNG IN EINEM COMPUTER MIT VARIABLEM GLEICHSTROMVERBRAUCHER.

摘要

A balanced three phase AC power supply for a computer system having unbalanced, variable DC loads. AC to DC converters utilize high power factor correction circuitry to impose a sinusoidal current loading waveshape substantially in phase with the AC voltage. Each AC to DC converter outputs equal DC voltages maintaining a balanced loading on the AC power source. The design and organization of the power supply components make the supply fault tolerant when one phase of AC power or one AC to DC converter is lost due to malfunction or servicing.
