Abstract: A power supply switching apparatus includes a first switching unit supplying power from a first conductive path to a first output path when the voltage of the first conductive path is greater than the voltage of a second conductive path, and supplies power from the second conductive path to the first output path. A second switching unit 80 supplies power from a fourth conductive path to a second output path when the voltage of a fourth conductive path is greater than the voltage of a third conductive path, and supplies power from the third conductive path to the second output path. An element unit allows a current to flow from the second conductive path to the third conductive path when the voltage of the third conductive path is smaller than the voltage of the second conductive path, and otherwise blocks a current.

Abstract: An energy supply device for reliably supplying energy to electrical loads, provides the energy supply by constant voltage sources. The number of constant voltage sources corresponds to the number of electrical loads. The energy supply device has a deactivatable balancing network. In this case, only the compensating currents are conducted via the balancing network, while the energy supply is provided via a direct electrical connection between the constant voltage source and the load. If a fault occurs, the balancing network can be deactivated. Faults in one branch thus do not affect the level of reliability of the energy supply in the remaining branches. After a faulty component has been located and isolated, the sources that are still intact, and the intact loads, can be brought back into operation by suitably configuring the balancing network. The availability of the drive system can thus be increased.

Abstract: A direct current power system includes a common direct current (DC) bus configured to supply power to a plurality of loads. A plurality of alternating current (AC) to DC converter bridges supply DC power to the common CD bus.
