Método para el suministro de consumidores eléctricos (3, 31, 32) de un vehículo con energía eléctrica mediante convertidores auxiliares (1, 11, 12) conectados paralelamente del lado de tensión alterna, donde en el caso de un cortocircuito a tierra se interrumpe el flujo de corriente entre los convertidores auxiliares (1,11, 12) y un conductor- N (N) conectado a tierra de una red de suministro de energía (2, 22), donde los convertidores auxiliares conectados paralelamente del lado de tensión alterna son operados con onda fundamental y sincronicidad del pulso.

    In a method for supplying an electrical load of a vehicle with electrical energy by auxiliary converters connected in parallel on the alternating-voltage side, a current flow between the auxiliary converters and a grounded N conductor of an energy supply network is interrupted in the presence a ground fault. The auxiliary converters connected in parallel on the alternating-voltage side are operated with fundamental-wave and pulse synchronicity. An energy supply system of a vehicle, in particular of a rail vehicle, performs this method, with the energy supply system including at least two auxiliary converters arranged in parallel, an energy supply network for supplying electrical loads, at least one switch for interrupting a current flow between the auxiliary converters and the energy supply network.
