Claim 0:
1. A power supply control system for use in a vehicle, the system comprising:
a first power control arrangement incorporating at least two first inputs and at least two first outputs and being operable in an active mode or in an isolated mode, wherein each input of the at least two first inputs is electrically connected to a corresponding one of the at least two first outputs in the active mode, and each first input of the at least two first inputs is electrically isolated from the corresponding one of the at least two first outputs in the isolated mode; and
a second power control arrangement incorporating at least two inputs second and at least two second outputs and being operable in an active mode or an isolated mode, wherein each input of the at least two second inputs is electrically connected to a corresponding one of the at least two second outputs in the active mode, and each second input of the at least two second inputs is electrically isolated from the corresponding one of the at least two second outputs in the isolated mode,
wherein the system further comprises:
a selector arrangement which is configured to select the active mode and the isolated mode of each of the first and second power control arrangements so that, at any one time, only one of the first and second power control arrangement operates in the active mode while the other of the first and second power control arrangement operates in the isolated mode;
a first DC/DC converter which comprises inputs that are coupled to the first outputs of the first power control arrangement;
a second DC/DC converter which comprises inputs that are coupled to the second outputs of the second power control arrangement;
a first output switch selectively connecting an output the first DC/DC converter and at least one device output configured to be electrically coupled to a component within a vehicle;
a second output switch selectively connecting an output the second DC/DC converter and the at least one device output; and
wherein the selector arrangement is further configured to control each of the first output switch and the second output switch to isolate a corresponding one of the first DC/DC converter and the second DC/DC converter from the at least one device output when the corresponding one of the first power control arrangement and the second power control arrangement is in the isolated mode.
