Abstract
The present invention relates to a device () for estimating an average value of an inductor current for switched-mode power converters (), the device () comprising: a sensor (), which is configured to measure an inductor voltage (v_L) and an inductor current (i_L); a ripple-suppressor (), which is configured to provide an estimated inductor current ripple (EIR) based on the measured inductor voltage (v_L); and a current-corrector (), which is configured to provide a corrected inductor current (i_Lc) based on the estimated inductor current ripple (EIR) and the measured inductor current (i_L).
