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 11):
An electrical apparatus, comprising:\n a switching converter including at least one inductor element coupled to an input node configured to receive an input voltage and a switch element coupled to the inductor element, the switch element including a control node configured to receive a command signal that controls switching of the switch element to generate an output voltage on an output node; and a control unit configured to generate the command signal having a switching period to control the switching of the switch element, and the control unit further configured to determine, in the switching period, a first time period in which an inductor current is flowing in the inductor element to store energy and a second time period in which energy is transferred to a load, said second time period having an end portion in which the inductor current drops to zero, the control unit configured to determine the duration of the first time period based on a comparison between a voltage indicative of a peak value of the inductor current and a reference voltage, the control unit including a pre-distortion stage configured to pre-distort the reference voltage to compensate for a corresponding distortion on an input current of the converter in relation to a desired sinusoidal trend of the input current caused by switching operation of the switching converter.
