THREE-CHANNEL POWER SUPPLY SYSTEM Russian patent published in 1995 - IPC

FIELD: radio engineering. SUBSTANCE: three-channel power supply system has D C power supply source, pulse generator, commutation unit and K power supply channels in accord with number of loads. Commutation unit is manufactured in the form of assemblage of K information paths each incorporating register of priority code, AND, OR, NOT gates, commutator composed of two AND gates and one OR gate. Each power supply channel includes section of M storage cells, M controlled key cells, tester of state of storage cells, pulse shaper, pulse distributor and logic AND and NOT gates. System enable charging of sections of storage cells of less important channels to be interrupted with emergence of request of section of storage cells of the most important power supply channels and order of priority of supply of channels to be changed in process of system functioning. EFFECT: enhanced reliability of D C power supply system. 4 dwg
