<p>The present invention relates to a switched mode power supply apparatus and a corresponding method. For an effective compensation of non linearities caused by dead time and voltage drops in the switching power amplifier of the apparatus an apparatus is proposed comprising a switching power amplifier (14) for amplifying a signal supplied by an external signal source (11) and for supplying a load voltage and/or load current to a load (15) and a control unit (12; 12b) for controlling the switching of said switching power amplifier based on a timing setting said control unit being adapted for simulating the behavior of the switching power amplifier by predicting the average load voltage and/or load current for at least two in particular a plurality of timing settings for a desired load voltage and/or load current based on state information about the present state of the switching power amplifier.</p> |
