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.
