Abstract
A short circuit detector is provided for a compact power supply system in which a plurality of power supplies may be operated in parallel. The detector senses when a voltage drop in a bus indicates a possible short and then energizes solid state devices to turn the system off for a prescribed period of time. After the prescribed period of time has passed, the system will attempt to restart. If the ground has been cleared, system operation will be restored. If not, the system will again be shut down for the prescribed period.
