A REVIEW PAPER BASED ON MULTI LEVEL INVERTER INTERFACING WITH SOLAR POWER GENERATION

Abstract

This paper proposes a new solar power generation system, which is composed of a DC/DC power converter and a new multi-level inverter. The DC/DC power converter integrates a DC-DC boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-degree inverter is configured the use of a capacitor selection circuit and a full-bridge electricity converter, related in cascade. The capacitor selection circuit converts the two output voltage sources of DC-DC power converter into a three-level DC voltage and the full-bridge power converter further converts this three-level DC voltage into a seven-level AC voltage. In this way, the proposed solar power generation system generates a sinusoidal output current that is in phase with the utility voltage and is fed into the utility The salient capabilities of the proposed seven-level inverter are that most effective six power electronic switches are used and handiest one energy digital transfer is switched at high frequency at any time. A prototype is advanced and tested to verify the performance of this proposed sun power era system.
