PERSONAL COMPUTER POWER SUPPLY Russian patent published in 1995 - IPC

FIELD: regulation of electric quantities. SUBSTANCE: power supply is essentially DC converter with two outputs, one of which is driving output and other is driven one. Stabilized voltage is maintained across driven output considering sampled proportional variation of loads at driven and driving outputs characteristic of personal computers. Power supply has RD circuit 13 to dispense with additional voltage regulator for second output, selective current sensor 16 enabling use of one protective unit for both outputs, resistor 15 inserted between feedback and reference-voltage inputs, control unit 9, and booster voltage unit 14 eliminating the necessity of additional reference-voltage source and reducing power of auxiliary power supply. EFFECT: reduced hardware expenses, improved reliability. 8 dwg
