N2 - LLC converters have been widely adopted in loads of industry applications. Although traditional fundamental harmonic based analysis method is simple, when applied in wide voltage gain range applications, the analysis accuracy degrades significantly. Thus, to optimize the converter performance, the time domain modelling analysis for different LLC converters and operation modes are discussed. Then, based on the modelling results, a simulation tool based on MATLAB graphical user interface (GUI) is developed to visualize the converter operation. Compared with the commercial simulation software, the developed one holds the advantages of fast, accurate, and convenient. The designed simulation tool has the exact simulation results as the commercial simulation software, while the simulation speed is much faster than the commercial ones. In addition, there is no need for users to build the different converter topologies and measure the key circuit currents and voltages, which is much more convenient. The developed simulation tool can be used to achieve automated design with thousands of iterations, which are tedious and time-consuming for commercial software. The time domain modelling and developed simulation tool are discussed. Simulation results comparisons between the developed simulation tool and commercial PSIM simulation tool are presented to validate the correctness and effectiveness of the developed simulation tool.
