This work presents a model-based frequency-locked loop (FLL) for three-phase systems subject to unbalance and harmonic distortion conditions. It is based on a pretty general model of a three-phase AC reference signal comprising a set of harmonic osci

This paper presents a control method to balance, in average, the DC-link capacitor voltages while injecting power to the grid using an h-bridge neutral-point clamped five-level inverter grid-tied through an LCL filter. The method exploits the structu
