A Solar Power Generation System with a Seven-Level Inverter

Abstract

This paper proposes another sunlight based force era framework, which is made out of a dc/dc power converter and another seven-level inverter. The dc/dc power converter coordinates a dc–dc support converter and a transformer to change over the yield voltage of the sun powered cell cluster into two autonomous voltage sources with various relationships. This new seven-level inverter is arranged utilizing a capacitor determination circuit and a full-connect power converter, associated in course. The capacitor choice circuit changes over the two yield voltage wellsprings of dc–dc force converter into a three-level dc voltage, and the full-connect power converter further changes over this three-level dc voltage into a seven-level air conditioning voltage. Along these lines, the proposed sun oriented force era framework produces a sinusoidal yield current that is in stage with the utility voltage and is nourished into the utility. The remarkable elements of the proposed seven-level inverter are that just six force electronic switches are utilized, and stand out force electronic switch is exchanged at high recurrence whenever. A model is produced and tried to check the execution of this proposed sun oriented force era framework.
