Single-phase three-level NPC inverters are useful for applications in residential areas, where a DC source is available, such as from Photo Voltaic (PV) source or Vehicle-to-Home (V2H) systems. This paper proposes a modeling approach of this type of inverter with SVPWM using a state-space approach, which can be an important tool for the analysis of the dynamics of the inverter when the load changes and for the design of a suitable controller. Since SVPWM is based in a vector approach, a hybrid model and a control scheme is proposed, successfully keeping the capacitors' balance. Simulation results show the inverter operation, the capacitors' voltage response and the output voltage.
