This paper explains a high efficient seven level inverter for PV electric generation system, which is collected of a dc/dc power converter and a new seven-level inverter. The dc/dc power converters incorporate a dc–dc boost converter and a transformer to change the output voltage of the solar cell array into two self-governing voltage sources with multiple associations. This new seven-level inverter is configured using a capacitor assortment circuit and a full-bridge power converter, associated in cascade. The capacitor assortment circuit changes the two output voltage sources of dc–dc power converter into a three-level dc voltage, and the full-bridge power converter additionally converts this three-level dc voltage into a seven-level ac voltage. Considering this technique, the projected solar PV electric generation system generates a sinusoidal productivity current that is in segment with the utility voltage and is fed into the service. The outstanding features of the prospect planned seven-level inverter are that only six power electronic switches are used, and only one power electronic switch is switched at elevated frequency at whichever time. A model is developed and experienced to authenticate the presentation of this projected solar power PV electric generation scheme.
