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 1):
A control unit configured to generate a command signal to control at least one switch element of a switching converter including the at least one switch element coupled to at least one inductor element, the at least one inductor element coupled to an input configured to receive an input voltage and an input current and having an output coupled to the at least one inductor element and configured to provide an output voltage, the control unit being configured to generate the command signal having a switching period to control the switching of the switch element and to determine, in said switching period, a first time period in which an inductor current is flowing in said at least one inductor element to store energy in said at least one inductor element, and a second time period in which energy is transferred from the said at least one inductor element to a load coupled to the output of the switching converter, said control unit configured to determine a duration of said first time period on the basis of a comparison between a peak value of the inductor current and a current reference that is a function of the input voltage and the output voltage of said voltage converter, and the control unit including a reference modification stage configured to modify a sensed value of the inductor current to compensate for distortion of the input current of the switching converter in relation to a desired sinusoidal trend introduced by a distortion factor caused by current ripple on said inductor current.
