Title:
METHODS FOR OPERATING PARALLEL AUXILIARY CONVERTERS IN A RAIL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/150137
Kind Code:
A3
Abstract:
The invention relates to methods for supplying electrical loads (3, 31, 32) of a vehicle with electrical energy by means of auxiliary converters (1, 11, 12) connected in parallel on the alternating-voltage side, wherein in the case of a ground fault, the current flow between the auxiliary converters (1, 11, 12) and a grounded N conductor (N) of an energy supply network (2, 22) is interrupted, and wherein the auxiliary converters connected in parallel on the alternating-voltage side are operated with fundamental-wave and pulse synchronicity. The invention further relates to an energy supply system (5) of a vehicle, in particular of a rail vehicle, for performing the aforementioned method, wherein the energy supply system (5) comprises at least two auxiliary converters (1, 11, 12) arranged in parallel, an energy supply network (2, 21, 22) for supplying electrical loads (3, 31, 32), at least one switch (4) for interrupting a current flow between the auxiliary converters (1, 11, 12), and the energy supply network (2, 21, 22).
