Analysis of LCLC DC-DC resonant converter in steady state operation

The paper deals with the operational analysis of resonant DC-DC converter, which is LCLC type. Main circuit of proposed converter consists of one series and one parallel LC branches. The output of the converter is expected to be DC, thus voltage diode rectifier is connected to output stage. At the beginning of the paper the topology of proposed converter is being described, whereby main focus is given for application field and on possibility of its variable use. Next, description of operation intervals is given. Considering DC output and voltage diode rectifier mathematical interpretation of state variables is derived for each operation interval. After it, simulation analysis is provided in order to verify mathematical interpretation of proposed converter.
