The invention relates to a circuit (1) for distributing power in an electric rail vehicle in order to supply voltage to one or more on-board electrical systems together with the traction drive from an external voltage tapped using a current collector, comprising a two-pole AC power bus (2) and at least three converters (3 to 6) connected to the AC power bus. One of the converters (3) is unidirectional and is designed to supply electric power to the AC power bus (2), and said converter is connected to a DC voltage intermediate circuit on the converter DC input (12) facing away from the AC power bus (2), said intermediate circuit being supplied via the current collector. Each converter (4 to 6) apart from the one converter (3) has a transformer (9 to 11) and a serial resonance circuit (7) connected to the two poles of the AC power bus. At least one of the converters (4 to 6) with a series resonance circuit (7) is a bidirectional converter.
