| description | This paper describes a new digital control method to enhance the dynamic performance of a dc-dc converter used in plasma display panel (PDP). A simple digital PID compensator with duty ratio feed-forward control is proposed to minimize the output voltage variation while the load current is continuously changing. The duty ratio feed-forward is calculated using noise-free load current information which is predicted by the available video data of the PDP. No separate current sensing circuit is required. A small signal z-domain feed-forward model is derived for the performance analysis and controller design. The proposed control method is experimentally verified on an asymmetrical half bridge dc-dc converter which supplies power to a 42 in PDP. |
