Abstract:
A control unit for a switching converter has an inductor element coupled to an input and a switch element coupled to the inductor element. The control unit generates a command signal with a switching period to control the switching of the switch element and to determine a first time period where an inductor current is flowing in the inductor element for storing energy and a second time period where energy is transferred to a load. The second time period has an end portion where the inductor current drops to zero. The control unit determines the duration of the first time period based on a comparison between a sensing voltage, indicative of the peak value of the inductor current, and a reference voltage. A pre-distortion stage pre-distorts the reference voltage in order to compensate for a corresponding distortion on an input current of the converter compared to a desired sinusoidal characteristic.

Claim (Index 14):
The electrical apparatus according to  claim 13 , further comprising:\n an input stage including said switching converter coupled to a power source configured to supply the input voltage; and an output stage configured to supply a regulated magnitude to a load as a function of the output voltage, the control unit configured to control a power factor correction in the power absorption of the power source.
