Abstract

PURPOSE: To assure an interruption-free power source device of its proper functioning by making it possible to control thyrister switches, respectively provided on output sides of a regular (or permanent) power source and a spare (or auxiliary) power source, with an ever-open contact and an ever-closed contact which reciprocally act conversely by a common gate logic electro magnetic relay.
CONSTITUTION: Thyrister switches 2 and 4 provided on respective output sides of a regular (or permanent) power source 1 and a spare (or auxiliary) power source 8 are designed to be controlled with an ever-open contact 11a and an ever-closed contact 11b which are to reciprocally act conversely by a common logic electromagnetic relay 11. In this mechanism, it is possible to make sure that either the thyrister switch 2 or the thyrister switch 4 is kept in a closed position so that a interruption-free power source device is assured of its proper functioning.
