SMPS CONVERTER CIRCUIT TOPOLOGIES—THE "BUCK" OR “FORWARD” CONVERTER

There are several circuit topologies that have evolved and are used in

switch mode power supplies (SMPS). We shall classify them into the

following groups, based on their operating principle:

1. the "buck" converter—also known as the forward converter;

2. the "boost" converter—also known as the "fly back" converter;

3. the "buck-boost" version of the "fly back" converter;

4. the Cuk converter.
