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 and generates a command signal having a switching period to switch the switch element and determine a first time period in which an inductor current is flowing in the inductor element for storing energy and a second time period in which energy is transferred to a load. An input current is distorted relative to a sinusoid by a distortion factor caused by current ripple on the inductor current. The duration of the first time period is determined based on a comparison between a peak value of the inductor current and a current reference that is a function of an output voltage of said voltage converter. A reference modification stage modifies one of the current reference and sensed value of the inductor current to compensate for distortion introduced by the distortion factor on the input current.

Claim (Index 7):
The control unit according to  claim 6 , wherein said optimization block further includes:\n a second voltage-controlled current source having a control input coupled to a third input of said control unit, the third input configured to receive a division of said input voltage and the second voltage-controlled current source configured to output a charging current having value that is a function of the input voltage according to the following expression:\n I CH =g ma K P V IN  \n where g ma  is a transconductance of the second current source and K P  is a division factor of said division of the input voltage:\n a charging capacitor having a capacitance C TR  that is coupled to said second current source and to be charged by said charging current during said first time period; and \n a maintenance capacitor having a capacitance C H , the maintenance configured to be selectively coupled to said charging capacitor and configured to maintain a value of a voltage across said charging capacitor at the end of said first time period to generate said command voltage of said first current source.
