A method for controlled connection of a plurality of on-board power system branches is disclosed, wherein electrical power is exchanged between first and third on-board power system branches if an uncritical supply state is present and electrical power is exchanged between second and the third on-board power system branches if a critical supply state is present in the first or third on-board power system branch. In a critical supply state, the first on-board power system branch is disconnected from the third on-board power system branch by opening a first switching device, and the second on-board power system branch is then connected to the third on-board power system branch via a second switching device. A second actuation device that actuates the second switching device receives a switch state signal from the first actuation device and closes the second switching device only if the received signal signals an open first switching device.

A power supply circuit (), particularly for a microcontroller of a transmission control unit, comprises a first output () supplying a first output voltage (U) and a second output () supplying a second output voltage (U), the first output voltage (U) being different from the second output voltage (U). The power supply circuit () also comprises a unit (OP, T, OP, T) adjusting the first (U) and second output voltage (U) and a controller (OP-OP, T, T) limiting the voltage difference between the first (U) and second output voltage (U).

Power supply circuit

The invention relates to a circuit configuration for determining the average value of an input signal (s), comprising a signal input () for receiving the input signal (s) and comprising a signal output () for outputting an output signal (g) that depicts the average value of the input signal (s). According to the invention, a counter () is placed between the signal input () and the signal output () in order to conduct an averaging. Said counter is preferably controlled by a sigma-delta modulator ().
