摘要： Method of controlling a current generator (1) having two voltage inputs (9, 10) and an output (13) connected to a load (6). In case the impedance of the load is lower than a first value, the generator is controlled in a non-feedback way to generate a signal, the current value of which is determined by the input voltage. On the other hand when the impedance of the load is higher than a second value larger than the first value, the output signal is negatively fed back to generate a signal on the output, the voltage value of which signal is determined by the input voltage. Thus, the output signal is automatically adapted to the desired mode of operation of the receiving apparatus (5). The invention also relates to an apparatus for carrying out the method.
