The purpose of this thesis is to investigate efficiency and load transient response
on three kinds of DC to DC buck converter topology. It's for getting the best efficiency
of DC to DC buck converters for portable electronic products. Therefore, the concept
of circuit design constitutes a low cost, low complexity and high efficiency system.
Based on two circuit topologies which are ESR and RfCf, the proposed mixed
circuit scheme is ESR+RfCf, also called hybrid. We derive the mathematical formula
for DC to DC buck converter to analyze efficiency, and also use the simulation and
experiments to prove analysis results. According to the analysis of all experimental
results, the next step is to draw the conclusion and make the rule. As a result, designers
understand disadvantages and advantages of three circuit topologies.
