The invention relates to a circuit arrangement for electrical power supply between a three-phase AC power network (2) and a traction DC power network (4), comprising a bidirectional converter arrangement (8) comprising an AC side (9) connected to the AC power network (2), a DC side connected to a DC bus (10) having a first line (11) on a first potential and a second line (12) on a second potential, the second potential being lower than the first potential and a filter (16), a diode rectifier (3) connected to the AC power network (2) and adapted for connecting to the traction DC power network (4) for electrical power flow to the traction DC power network (4), and a bidirectional current and at least unidirectional voltage semiconductor switching device (13, 14) connected to the DC bus (10) and adapted for connecting to the traction DC power network (4) for allowing a uncontrolled energy flow from the DC power network (4) to the DC bus (10).
