Evaluation and Verification of LLC Operating Regimes

The paper presents a study of the operating regimes of a LLC resonant converter using mathematical models and real hardware measurements for verification. The various operation waveforms are taken with varying the load, thus changing the output parameters (current, voltage and power) of the converter. The parameters of the circuit elements that are loaded in the model are the same as of the evaluation board TMDSHVRESLLCKIT from Texas Instruments. The results from the internal study of this board's operating regimes are used to verify the results produced from the resonant converter model.
