Embodiment Construction

[0028] exist image 3 It can be seen in the figure that the engine control circuit 10 is applied with the mains DC voltage Udc at its input E10. On the output side, motor control circuit 10 generates a motor drive voltage at output A10 , which is denoted by the reference Umotor and can be, for example, a three-phase voltage.

[0029] On the input side, the motor control circuit 10 has a step-up converter 20 , after which a pulse-modulated inverter 30 is connected. The step-up converter 20 is actuated by a control device 40 in which a setpoint intermediate circuit DC voltage Unenn is predefined either fixedly or within certain limits.

[0030] The control device 40 is connected on the input side indirectly or directly to the input E10 of the engine control circuit 10 , so that the mains DC voltage Udc or a measured value corresponding to the mains DC voltage Udc can also be supplied to the control device 40 .

[0031]At the output A40, the control device 40 generates a contro...

Abstract

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.
