  "textContent": "The invention relates to methods for supplying electrical loads (3,31,32) of a vehicle with electrical energy by means of auxiliary converter units (1,11,12) connected in parallel on the AC voltage side, wherein in the case of a ground fault the current flow between auxiliary converter unit (1,11,12) and a grounded neutral conductor (N) of a power supply network (2,22) is interrupted, and wherein the auxiliary converter units connected in parallel on the AC voltage side are operated in fundamental frequency and pulse synchronization. Furthermore, the invention relates to a power supply system (5) of a vehicle, in particular a rail vehicle, for carrying out the aforementioned method, wherein the power supply system (5) comprises - at least two auxiliary converter units (1,11,12) arranged in parallel - a power supply network (2,21,22) for supplying electrical loads (3,31,32) - at least one switch (4) for interrupting a current flow between auxiliary converter unit (1,11,12) and power supply network (2,21,22).",
