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 11):
A switching converter, comprising:\n switching converter circuitry including a switch element coupled to an inductor element, the inductor element coupled to an input configured to receive an input voltage and an input current and the switching converter circuitry further including an output configured to be coupled to a load and coupled to the inductor element, the switch element configured to receive a command signal that controls switching of the switch element to generate an output voltage on the output; and a control unit configured to generate the command signal having a switching period to control the switching of the switch element, the control unit configured to determine during the switching period a first time period where an inductor current flows in the inductor element to store energy in the inductor element and to determine during the switching period a second time period where energy is transferred from the inductor element to the load coupled to the output, the control unit configured to determine a duration of the first time period based on 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, and the control unit further configured to sense a value of the inductor current in the inductor and to adjust a value of one of the current reference and the sensed value of the inductor current to compensate for distortion of the input current.
