초록
In many multiple output SMPS, the cross regulation between the output voltage is so poor that the linear regulator is usually added to avoid this problem. Therefore, manufacturing cost is increased. In this paper, the TTFC(Two Transistor Forward Converter) using the magamp was presented to obtain better cross regulation between the multiple output SMPS. Also, as the synchronous rectifier was applied in the secondary section, whole efficiency can be improved. In this paper, the mode analyses in steady slate and experimental results of the prototype to verify the validity of the presented converter are presented and discussed.
