Abstract

A driving arrangement is provided for driving a load, comprising a driver input for receiving an input power and a driver output to be coupled to the load. A high frequency switch mode PFC converter converts the input power to a PFC converter power and a high frequency switch mode regulator has an output connected in series with the output of the PFC converter. A superimposed power from the PFC converter and the regulator with synchronized high frequency switching is provided to the load. This enables a high frequency ripple to be at least partially cancelled. Wherein the charging phase of the PFC converter at least partially overlaps with the first phase of the regulator in which phase the regulated power increases.
