This report presents literature and detailed theory of the synchronous converter. The objective of the project is to Design and analyze synchronous d. c. to d.c. converter. Synchronous rectification could be found in two main circuit topologies (i) Forward converters and (ii) flyback converter. The Flyback converter is a d.c. to d.c. converter. The author analyzed both converter types and came up with successful results. Synchronous Conversion is a growing concept; where the main objective is to reduce down power losses during rectification of power. By using synchronous rectifiers we manage to minimize the size of the power supplies used in portable appliances like Laptops and Mobile phones. In order to design and analyze the circuit some parameters are to be fixed like; operating frequency as 300 KHz, primary voltage for transformer as 15 V de, secondary voltage as 3.3 Vdc and the output current as 0.8A. Any Mobile Phone charger is having the same parameters. The author can claim that this would not be the conventional/normal Mobile Phone charger as Synchronous rectification concept is used.
