A new switched-capacitor multilevel inverter with soft start and

The main challenge is to provide a high-quality AC voltage at a low cost. The DC/AC voltage source inverter (VSI) is the main component used as an interface between the PV and the AC network. The PV panels can be directly connected to the VSI or through a boost stage, which depends on the employed VSI topology and the PV panel voltage level.
