DESIGN AND ANALYSIS OF SYNCHRONOUS DC-DC CONVERTER

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.
