Abstract:
A method for the alternating operation of power supply units for a device which has at least two power supply units is disclosed. An alternating operation of the at least two power supply units is supplied by a switchover between the two power supply units if the two power supply units are functional. With alternating operation, the power supply unit that is in operation contributes to the power supply for the device, whereas the power supply unit that is not in operation, is cut off from supplying power to the device. In the case of a failure of the power supply unit which is in operation at the moment, an immediate switchover between the at least two power supply units is provided for.
