“…Subsequently, staggered inverters utilizing more DC sources are supported monetarily [7]- [9]. Consequently, a capacitor has been set in the U-Cell topology as the reliant second source and a few controllers [12] have been intended to keep the voltage (V2) consistent at the 33% degree of the reference voltage (V1). The yield voltage waveform (Vab) and DC capacitor current got by simulation.…”

This paper proposes a single phase modified seven level U-Cell inverter configurations in which the advanced process controller has been implemented. By using the boost operation the output of the inverter will produce higher output voltage when compared to the maximum DC source value used. To obtain maximum power the designed inverter is implemented with the photovoltaic system where the power is produced from two different PV panels which is connected to DC link by using DC-DC converters. The semiconductor switches and DC links are used to generate the inverter AC output voltages with seven levels. Two PV panels with different voltages are used in which two panels voltages are combined and their powers are injected to the grid. To validate the dynamic performance of the proposed U-Cell inverter the advanced process controller is used in the inverter connected to the grid. The controller is designed and processed to maintain the capacitor voltage to obtain the desired AC output with desired magnitude. The dynamic performance during changes in the supply current and DC voltage of capacitor for the process controller has been obtained.
