摘要：
The invention relates to a motor activation circuit (10) for a rail vehicle having a boost converter, which is disposed at the input of the motor activation circuit, and which converts a mains DC voltage (Udc), which is applied at the input of the motor activation circuit, into an intermediate circuit DC voltage (Uzk), a pulse rectifier, which is downstream from the boost converter, and which can be connected at the output to a drive motor of the rail vehicle and is capable of converting the intermediate circuit DC voltage of the boost converter into a motor drive voltage for driving the drive motor, and a control unit, which activates the boost converter and which activates the boost converter in operation such that said converter generates the predetermined rated intermediate circuit DC voltage for a mains DC voltage below a predetermined rated intermediate circuit DC voltage as the intermediate circuit DC voltage. According to the invention, the control unit is designed such that it activates the boost converter (20) for a mains DC voltage (Udc) above the rated intermediate circuit DC voltage (Unenn) such that said converter generates an intermediate circuit DC voltage (Uzk) identical to the mains DC voltage (Udc) or an intermediate circuit DC voltage, which is greater at most by a predetermined offset value (Uoffset), and feeds said intermediate circuit DC voltage into the pulse rectifier.
