Series Resonant High Frequency Link Sine-wave Inverter System Modeling using Sampled Data

Based on the detailed analysis of the series resonant high frequency link sine-wave inverter operational principle, a system modeling methodology is presented using the sampled data. For this special modeling application, a black-box approach is described based on the data which are gotten from simulation or experimental results. And this approach aims at generating discrete-time small-signal linear equivalent model which describes the inverter as a linear time-invariant system, so the knowledge of the linear system can be used to the identified model for constructed feedback controller. The identified model is verified by the simulation and experimental results
