Abstract
The present invention concerns an absorption circuit () for absorbing a power ripple intended to be connected in parallel to a piece of electrical equipment powered by a power factor correction circuit (), said absorption circuit () being a step down voltage circuit comprising: —a capacitor () mounted in series with an inductor () and at least one switch (), —a control module (), —means () for measuring a first current (I) intended to power said electrical equipment, the switch () being controlled by the control module () to vary the charging of the capacitor on the basis of the ripple of the first current (I) in order to attenuate the power ripple, and said circuit further comprising means () for measuring the voltage (Vc) at the terminals of the capacitor (), and the control module () being configured to control a second current (Ic) flowing through the capacitor () in such a way that the voltage (Vc) at the terminals of the capacitor () remains within a predefined interval.
