TRANSFORMERLESS-INPUT POWER SUPPLY Russian patent published in 1996 - IPC

Abstract RU 2056698 C1

FIELD: secondary power supplies. SUBSTANCE: power supply has d.c. voltage changer 3 connected through transformer 5, rectifier 6, transistor regulator 7, and filter 8 to output terminal loads which are connected to feedback assemblies. Diode switch 14, two comparators 17,18, and matching resistors 12,13 introduced in power supply enable shifting in time turn-on and turn-off moments of transistors 4 in changer 3 and transistors of regulator 7 connecting load to power supply. EFFECT: improved design. 2 dwg
