The invention relates to a device and method for discharging an energy accumulator (C), in particular an intermediate circuit capacitor, in a high-voltage grid (3), in particular in a direct current intermediate circuit in a motor vehicle, having a direct current converter (5) connected downstream of the high-voltage grid (3), a low-voltage grid (4) connected downstream of the direct current converter (5), an power grid (7) connected downstream of the direct current converter (5) and parallel to the low-voltage grid (4) for supplying energy to a control circuit (9) of the direct current converter (5), and a first controllable switching element (S) which is connected to the connecting line between the direct current converter (5) and the low-voltage grid (4) and by means of which, in the event of a disturbance of the low-voltage grid (4), the direct current converter (5) and the power grid (7) can be disconnected from the low-voltage grid (4). The power grid (7) is connected to the direct current converter (5) via a first electrical component (10; 20) which prevents a backflow of current from the power grid (7) into the direct current converter (5).
摘要:
A method for assigning addresses in a system having a first generator unit and at least one further generator unit positioned in parallel to the first generator unit. Each of the generator units has a control-signal input and a control-signal output. The control-signal input of each further generator unit is connected in each instance to the control-signal output of another of the generator units. Each of the further generator units receives an identification signal output at the control-signal output of a generator unit upstream of it, and assigns itself an individual address as a function of the respective identification signal received, the address depending on the length of the identification signal received.

The present invention discloses a protection apparatus for an IT network having a first and a second live line, having a signal generator which is designed to feed a first signal to the first and/or to the second live line, having a detection device which is designed to detect the profile of the fed first signal in at least one live line, and having a control device which is designed to analyse the detected profile and to output a disconnection signal when the analysis of the detected profile indicates that a living organism is in contact with the first live line and the second live line. The present invention also discloses a method and a power supply system.
摘要:
In a method for controlling a group of at least two electrical generators which supply a motor vehicle electrical system, each individual generator of the group provides a generator workload value, which indicates a workload of the individual generator, to each other one of the group of generators. The workload values represent an absolute value which indicates an actual power which is generated by the individual generator. Alternatively, the workload values represent a relative value, which indicates a ratio of the actual power to a nominal power of the individual generator.

A device for voltage supply includes a first generator and a second generator connected in parallel to it. A control unit is also provided, to which capacity utilization signals are made available by the first and the second generator. By an evaluation of the capacity utilization signals, the control unit ascertains control signals, which lead to a uniform load distribution with respect to the generators.

The present invention relates to a method and a device for assigning addresses in a system having a plurality of generator units connected in parallel. After receiving a start signal, the first generator unit assigns itself an individual address and outputs an identification signal at its control-signal output. Each of the further generator units receives an identification signal output at the control-signal output of a generator unit upstream of it, and assigns itself an individual address as a function of the identification signal received in each case.
摘要:
A method and a device are provided for providing a supply voltage for the consumers of a vehicle electrical system, using generator units connected in parallel. The measurement voltage inputs and the monitor outputs of the controllers of the generator units are used in the initialization phase for the assignment of master or slave function, as well as for address assignment if warranted, and during later parallel operation are used to bring the degree of utilization of the generators of the generator units connected in parallel into agreement.
