Abstract This paper presents the TTFC(Two Transistor Forward Converter) using Synchronous Rectifier. The two transistor forward circuit is used to decrease voltage stress of primary side and the synchronous rectifier is used to reduce current stress of secondary side. This paper compared with diode rectifier and synchronous rectifier of two transistor forward converter. The principle of operation, feature and design considerations are illustrated and verified through the experiment with a 200W 100㎑ MOSFET based experimental circuit.
