Z-source based NPC three level inverter for photovoltaic system using SPWM technique

摘要

The Z-source concept has many advantages it can be applied for any type of power conditioning system this paper propose a Z-source based three level inverter system for the photo-voltaic array or system. A comparison of traditional system and new Z source three level inverter configuration is performed. In this paper present the SPWM technique for controlling the neutral clamped three level inverter. This gives us the more advantages over system harmonics and proper inverter control. The proposed system performance of Experiment is validated using simulation.
