Abstract
An apparatus for selectively coupling a system with a first power supply or a second power supply includes: (a) a first switch for effecting a first coupling of the system with the first power supply; (b) a second switch for effecting a second coupling of the system with the second power supply; (c) a first switch control unit coupled for controlling the first switch; (d) a second switch control unit coupled for controlling the second switch; (e) a connection director unit coupled with the first and second switch control units for providing control signals to effect the first and second coupling; at least one of the first and second coupling being effected as an initial coupling establishing a generally time-dependent increasing current between the system and one power supply and a continuing coupling establishing a substantially constant operating current between the system and the one power supply.
