摘要：
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 A 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.
