Abstract:
Apparatus comprisinga plurality of power supplies each generating an output voltage signal that is supplied to a system load common to the power supplies;a plurality of isolating devices having one terminal connected to the output of a respective one of the power supplies and having another terminal connected to a connection point extending to the system load to isolate the outputs of the power supplies from one another; anda plurality of signal sensing paths connected at one end to a first input of a respective one of the power supplies and connected at the other end to the connection point to provide a feedback signal derived as a function of a voltage signal supplied to the system load and a voltage signal outputted by the respective one of the power supplies, and wherein each of the power supplies includes signal regulation apparatus that changes the level of the voltage signal that the power supply outputs as a function of the level of the feedback signal that the power supply receives via its respective signal sensing path and level of a preset signal connected to a respective second input.
