ANALYSIS OF SOLAR POWER GENERATION WITH A MULTILEVEL INVERTER

MASTER OF ENGINEERING

— In this paper a solar power generation system with a multilevel inverter, which is consist of a DC/DC power converter and a new grid connected solar seven-level pulse-width modulated (PWM) inverter. The DC/DC boost converter and a transformer to convert the output voltage of the solar cell into two self-determining voltage sources with numerous relationships integrate by DC/DC power converter. This new seven-level inverter is configured using a capacitor selection circuit and a full-bridge power converter, connected in cascaded. 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 which 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. This inverter consist of only six power electronics switch, and using only one power electronic switch is switched at high frequency at any time this is salient features of a project. A model is developed and tested to verify the performance of proposed solar power generation.
