This paper presents a Lyapunov stability theory-based control technique for a single-phase quasi-impedance source neutral-point-clamped (qZS-NPC) inverter with LCL filter. The proposed control technique handles two control objectives, which are the grid current control and the dc-link voltage control. The dynamic and steady-state performances of the proposed control method have been demonstrated by simulations using Matlab/Simulink.
