Abstract
A synchronization device for a redundant power supply system synchronizes resetting of tripping type current limiter devices which are reset automatically, to prevent the current limiters tripping out in cascade when the system is started up or automatically reset after the disappearance of a short-term current surge. It includes a synchronization link interconnecting all the current limiters of all the power supply units. Each current limiter includes a generator sending a synchronization signal on the synchronization link periodically and independently for each current limiter. The generator which sends a synchronization signal first resets all the current limiters simultaneously. The device has applications in electronic equipment comprising a plurality of power supply units connected in parallel.
