(a) Draw circuit diagrams of two basic half-bridge resonant DC-DC converters (the series and parallel resonant converters) and write down the expression of the output voltage related to the input voltage for each resonant DC-DC Converter

b) Draw LLC resonant converters with a full-bridge or a half-bridge circuit on the primary side. Explain the difference between each other. (refer to "Infineon-Design_example_resonant_LLC_converter_operation_and _design").
