Double-loop SVPWM control strategy for multi-level inverter based on LC filter

Space vector pulse width modulation(SVPWM) for got the hot-spot study rapidly in recently years. Compared with SPWM, SVPWM has a higher ratio of output voltage, lower content of total harmonic distortion(THD) and make digitization reality easier. Furtherly, based on traditional SVPWM strategy, using double-loop method can improve responsivity and less THD. The proposed strategy system was simulated under the circumstance of Matlab/Simulink. Finally, the feasibility and effectiveness of the proposed method was verified by simulation results.
