Abstract:
An active wire compensation circuit, adapted to compensate a level of an output voltage detecting signal, is disclosed. A feedback controller controls a converting circuit according to the compensated output voltage detecting signal to have a load voltage for driving a load stabilized at a predetermined voltage level. The active wire compensation circuit comprises a compensating unit and a feedback compensating unit. The compensating unit detects the load current flowing through the load and accordingly generates a compensating current. The feedback compensating unit modulates the level of the output voltage detecting signal according to the compensating current and generates the compensated output voltage detecting signal.
