Adjust the auxiliary transformer turns ratio, change the original edge number of turns Np, reduce the former vice edge of turns ratio, reduce low voltage when the duty ratio, is far smaller than that of UC3844 the upper limit of 45%;UC3844 current feedback link RC filter network for parameter adjustment, groped through the experiment many times, he won at lastThe parameters of the ideal, filter capacitor.Again under the same conditions to test the same pair of auxiliary transformer winding.

High Qualilty,
As a Result of Professionalization

MIWE Group Corporation is looking forward to the long,
firm and win-win cooperation with you.
