Embodiment Construction

[0052] figure 1 An embodiment of an energy transmission device 10 is shown schematically, which has an electromagnetic converter unit 12 which can be connected on the input side to an alternating voltage source 14 , in the present case to an alternating voltage source 14 . An energy supply grid 14 is coupled. The energy transmission device 10 can be installed, for example, in figure 1 In the case of an electric vehicle or a plug-in hybrid vehicle not shown in detail, the electric vehicle or plug-in hybrid vehicle has a traction battery 16 and an on-board electrical system battery 18 . Furthermore, electric vehicles or hybrid vehicles have an electric machine which serves as a drive motor and which is supplied with electrical energy via traction battery 16 . In this case, traction battery 16 is assigned a high-voltage onboard electrical system, which typically has a voltage of greater than 120V. Furthermore, on-board battery 18 is coupled to a low-voltage on-board power syst...

Abstract

The invention relates to a power transmission arrangement (10) having an electromagnetic convertor unit (12), the input side of which can be coupled to an AC voltage source (14), a first DC voltage circuit (36), the input side of which is coupled to the electromagnetic converter unit (12) and the output side of which can be coupled to a first electrical DC voltage sink (16), and which is designed to provide a first DC voltage on the output side, and a second DC voltage circuit (40), the input side of which is coupled to the electromagnetic converter unit (12) and the output side of which can be coupled to a second electrical DC voltage sink (18), and which is designed to provide a second DC voltage on the output side, wherein one of the DC voltage circuits (36, 40) has a DC voltage converter (50) for the purpose of adjusting its output-side DC voltage.

Description

technical field [0001] The invention relates to an energy transmission device having an electromagnetic converter unit which can be coupled on the input side to an alternating voltage source. Background technique [0002] It is known in the field of motor vehicle drive technology to use an electric motor as the sole drive or together with another type of drive motor (hybrid drive). An induction motor is typically used as a drive motor in such an electric vehicle or a hybrid vehicle. Power electronics are used to control such an induction machine in a motor vehicle, including an inverter that converts the DC voltage / DC current of the high-voltage battery on board the motor vehicle into alternating current. The inverter is controlled by the control unit in such a way that the electric machine generates a defined rotational torque on the drive shaft of the electric machine at a defined rotational speed during motor operation. Thus, the high voltage battery of the motor vehicl...
