Abstract :

A compelling control technique, including framework level control and heartbeat width tweak for semi Z-source course multilevel inverter (qZSCMI) based network tie photovoltaic (PV) control system is proposed. The system level control accomplishes the network tie current infusion, autonomous most extreme power point following (MPPT) for partitioned PV boards, and dc-connect voltage adjust for all semi Z-source H-connect inverter (qZS-HBI) modules.
