A switched converter

Abstract

The invention relates to a switched converter, supplied with a DC voltage originating from an AC voltage, preferably mains voltage. The switched converter comprises output terminals for supplying an LED load, a feed-back loop controller configured to generate an output signal setting a switching frequency of at least one switch of the converter for controlling a load current on a nominal value, based on a signal indicating the load current and supplied to the feedback loop controller and a feed-forward control, FFC, block, wherein a response time of the FFC block is faster than a response time of the feed-back loop controller. The FFC block is configured to analyze, preferably in time increments said load current sensing signal and / or the DC signal a ripple amplitude component present in said signals and to add, based thereon, a ripple compensation signal to said output signal of the feed-back loop controller.
