NO-BREAK POWER SUPPLY FACILITY Russian patent published in 1995 - IPC

FIELD: power supply for computing and data-processing centers, control centers, and communication equipment. SUBSTANCE: power supply facility has a.c. power buses, working and charging rectifiers, storage battery, two inverters, and in addition it is provided with short-out nonlinear resistance box inserted in series with storage battery "minus" bus, and power diodes whose positive poles are connected to common "minus" buses of working rectifiers, respectively. Facility is also provided with low-current rectifier permanently connected through current relay to storage battery; normally open contacts of relay are connected in parallel to start button of charging rectifier; working rectifiers are, essentially, voltage regulators and charging rectifier functions as current regulator; inverter functions as CW generator. EFFECT: provision for reliable power supply, improved stability of output parameters of a!c! and d!c! currents. 4 cl, 1 dwg
