In this paper, an analysis of series connected Forward Flyback converter is carried out. SFFB (series connected Forward Flyback converter) is a type of forward and fly back converter which shares the transformer for increasing its utilization factor. The SFFB converter has a series-connected output for high boosting voltage transfer gain. However, few predefined topologies are available for the power conversion based on voltage boost that has poor efficiency due to the lack of isolation. In the arranged SFFB (arrangement associated Forward Flyback converter) has a change for security, framework relentlessness, galvanic separation and high transformation proficiency. A few promising application like request detachment, the SFFB is the one, which suits the necessity of such applications. The PIC (Peripheral Interface Controller) controller is utilized to give activating heartbeat to the converter switch, in this way streamlining its operation and gives better productivity by method for controlling the yield. The operating standard and design rule of the planned converter is developed and the performance is analyzed in a simulation. This converter has four operation modes when the turn ratio of the second and the third windings of the transformer is set to be a certain value. In addition, it achieves high-energy efficiency from low load to high load condition by reducing the required power level for DC/DC converter by one-third of conventional DC/DC converter.
