Abstract

The modified emitter follower compensation circuit is discussed and the principle of a slop compensation circuit is also analyzed. Focusing on transformer primary side existing current peak when duty ratio of peak current-mode control power converter is higher than one half. Theoretical analysis shows that this circuit can eliminate the phenomenon of current peak, increased the range of the duty ratio and increase the efficiency of transformer. Develope a 12V/1700A rare earth electrolysis power model machine. Experiment shows that this compensation circuit can eliminate the transformer primary side current-peak phenomenon and makes the operation of the power stable and reliable.
