STABILIZING ELECTRIC POWER SUPPLY SOURCE Russian patent published in 1994 - IPC

FIELD: electric power supply of device in measurement technology, automatics and computer engineering. SUBSTANCE: device has output transformer 1, rectifier 4, regulating device 6 made on the basis of two transformers 7 and 9; resistor 10; two transistors 11, 12; comparison unit 13, reference voltage source 14, resistive voltage divider 15; capacitor 16. Transistor 12 with resistor 10 serving as a current sensor protect transistor 11 from overcurrent to enhanced reliability of the device. EFFECT: enhanced efficiency due to regulating device 6 made on the basis of two transformers 7, 9 and due to connection of their primary windings opposite in phase. 1 dwg
