Resonant converters for electric equipment power supply

The paper deals with the use of resonant converters for the power supply of electric equipment. After exploring the advantages of using the resonant conversion, an analysis of the three main resonant topologies, namely i) series-resonant, ii) parallel-resonant, and iii) a combination of them, is carried out and a series resonant converter is implemented. Considerations on the design of the resonant converter as well as on the selection of their components, including the HF transformer, are presented. Performance of the implemented series resonant converter is investigated in terms of dynamic behavior through experimental results.
