Abstract (en)
[origin: WO2013152373A1] An operating device (2) for an illuminant (3) comprises a power factor correction circuit (20), a transformer (30), which is connected to the power factor correction circuit (20) and has an output (41) for supplying power to the illuminant (3), and a control device (14) having an input (51) for sensing the voltage (Vbus) that is provided for the transformer (30) by the power factor correction circuit (20). The control device (14) is set up to perform an evaluation of voltage ripples in the voltage (Vbus) and to take the evaluation as a basis for determining a load (3) connected to the output (41) of the transformer (30) and/or an output power from the transformer (30).
