Redundant power system switch for backup power switching without power interruption
Abstract:
A redundant power system may include a first switch that connects between a redundant power source and a first remote system, a second switch that connects between the redundant power source and a second remote system, and a control circuit. The control circuit may apply a first control signal to the first switch to cause the redundant power source to connect through the first switch to the first remote system via a switched connection. The control circuit may determine if the second remote system requires power, and may apply a second control signal to the first switch to open the switched connection when the high priority remote system requires power. The control circuit may apply a third control signal to the second switch, upon an expiration of a delay timer, to cause the redundant power source to connect through the second switch to the second remote system.
