CONTROL MODULE WITH AN ESTIMATOR OF AN INPUT ELECTRIC QUANTITY FOR A SWITCHING CONVERTER AND METHOD FOR CONTROLLING A SWITCHING CONVERTER

摘要

Described herein is a module for controlling a switching converter, which includes at least one inductor element and one switch element and generates an output electric quantity starting from an input electric quantity. The control module generates a command signal for controlling the switching of the switch element and includes an estimator stage, which generates an estimation signal proportional to the input electric quantity, on the basis of the command signal and of an input signal indicating a time interval in which the inductor element is demagnetized. The control module generates the command signal on the basis of the estimation signal.
