Abstract:
An AC/DC PFC converter comprises an LLC PFC pre-regulator and a DC/DC converter output stage. The output stage has a feedback unit adapted to provide a feedback signal (in addition to the conventional feedback of the bus voltage error) to the control circuit of the PFC pre-regulator for modulating the controlled output voltage of the PFC pre-regulator in dependence on the output power and/or the input current and voltage. In this way, the total harmonic distortion of the input of the converter can be reduced by controlling the gate switching in the PFC pre-regulator.
