Abstract
As the demand for renewable energy increases, there have been tremendous advancements in power electronics conversion, specifically in solar photovoltaics (PVs). In this research, we will explore the use of advanced discontinuous pulse width modulation (DPWM) methods on the NPC inverter that is powered from the solar PV. Our main aim is to increase efficiency while ensuring that switching losses and voltage balancing at the dc-link capacitors are maintained. Our DPWM approach provides an efficient method that increases the performance of the NPC inverter by decreasing the number of switching transitions and also optimizing the modulation process. Besides, our method also decreases stresses on switching components and ensures that better harmonic performance is achieved. Our model will be simulated to check the performance of the system at different operation conditions.
