This project proposes a new solar power generation system, which is composed of a DC-DC power converter and a new seven 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-level inverter is configured using a capacitor selecti0on 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 converter into a three-level DC voltage into a seven-level ac voltage. In this way, the proposed solar power generation system generated a sinusoidal output current that is in phase with the utility voltage and is fed into the utility. The salient features of the proposed seven-level inverter are that only six power electronic switches are used, and only one power electronic switch is switched at high frequency at ant time.
