Abstract

In a conventional solar power plant, DC input voltage to the inverter is fed from the multiple solar panels with series parallel combination. So the maximum power point tracking (MPPT) is possible only on the series parallel combination of all the arrays together, which is not so efficient. Independent maximum power point tracking (MPPT) is needed to improve the system efficiency. Independent control of the voltage is possible through the cascaded inverters. Hence, independent MPPT control can be obtained by using cascaded H-Bridge-based inverters for PV applications. In this paper, decoupled control of active and reactive powers for a CHB inverter in PV applications is explained and the simulation results are presented. System operation with equal and unequal irradiances on PV arrays is also explained.
