Abstract
The present invention relates to a method and a device for diversion of power in an electric circuit (,), e.g. a subscriber circuit with a balanced two-wire transmission, comprising a user (,) with a variable voltage requirement, which is controlled by the supply characteristic of the device and the resistance in the two-wire transmission (A,B,L). The voltage requirement of the user is fed back via a reference signal (U,) to an input of a voltage-regulating circuit (,), which supplies the user with a drive voltage (V,) adapted to the value of the reference signal. The voltage-regulating circuit (,) is fed with a supply voltage (V,) and a regulator voltage (V,) is defined as the difference between the drive voltage (V,) and the supply voltage (V,). Parallel with the voltage-regulating circuit, an external device (,), e.g. a resistance, is connected in order to divert an undesired power generation in the voltage-regulating circuit through the whole or part of the supply current of the user being led to the external resistance and there the whole or part of the power generation is emitted.
