Analysis and Small Signal Modeling of Five-Level Series Resonant Inverter

This paper explains the implementation of a small-signal model for new five-level series resonant inverter structure. The proposed circuit combines advantages multilevel inverters and characteristics physical phenomena, resonance. offers possibility to design linearized linear time-invariant (LTI) around an equilibrium point based on first-order Taylor series. After that, performance its are evaluated in MATLAB/Simulink environment. Compared with MATLAB generated using system identification toolbox, developed exhibited good accuracy frequency time domains. In addition, hardware test bench is validate model. Both simulation experimental results show that very interesting high-voltage high-frequency applications. As perspective, from obtained, we suggest use AC analysis modeling. contains rich information recently used tools dynamic systems modeling nonlinear processes can be applied analyzing other power electronics inverters.
