Abstract:

 In Renewable systems, a inverter is main devices which are used for power conversion. Usually multilevel inverters are adopted for this purpose. This project deals with a Seven-Level inverter topology that follows this trend. A review of the state of the art of the Seven-Level topology and a solar power stabilization are the proposed solution of this project. The proposed inverter architecture is based on thefull-bridge topology with two additional power switches and two diodes which is connected to the midpoint of the dc link. The T noraditional converter has less number of switching devices to reduce the loss and cost. Since the two added levels are obtained by the discharge of the two capacitors of the dc link, the balancing of the midpoint voltage is obtained with a specific (Plz specify which type) pulse width modulation (PWM) strategy. Simulation and experimental results has shown the effectiveness of the solution.
