Реферат: ABSTRACT: High voltage a.c. to low voltage d.c. swit-ching interface circuit. High voltage mains a.c. is per-manently connected via a first potential divider to the set input of an i.c. bistable circuit, and is connected via a high voltage switch and a second potential divider to the reset input of the bistable circuit. The poten-tial ratios of the two dividers are chosen so that when the switch is closed the bistable circuit is set and remains set.
