The objective of this thesis is to study the basic resonant converter topologies for switching power supplies and to compare their performance under different operating conditions. The series and parallel resonant converters are analyzed in detail. The analysis uses the state plane method, which gives a good insight of the operation of the converter. It is found that these converters have more desirable characteristics when operated at a frequency above the resonant frequency rather than below it. Analytical results are verified by sinlulation and experiment.
