Cascaded Multilevel Inverter for Photovoltaic Systems With PI Control

Authors: Shantanu Chatterjee, S Mallika

Use of renewable Energy such as solar, wind, water, nuclear energy etc is of huge demand in recent era. Converters used in Photovoltaic Systems have two stages: a boost up chopper and a PWM inverter. But this integration of these two stages have certain problems like decrease in efficiency, problem in interaction between the stages and also problem in MPPT(i.e Maximum Power Point Tracking) etc. So the Total energy which is produced is not utilized fully rather only a part of it can be utilized fruitfully. So in this paper we have proposed a novel use of Cascaded H-Bridge Multilevel Inverter Tropology in integrations with PV module controlled by a PI controller. The usefulness of this tropology is in the use of fully controlled PI controller and the increase in system performance. All the Gate Pulses to the IGBT switches are provided by the FPGA (Field Programmable Gate Array) kit. The detailed discussion and performance of the whole system alone with the block diagram and basic designing is discussed in this paper. Simulated Results and comparison is also done in this paper. This System provide a results in more efficiency and specially in low or medium power application. Detailed harmonic discussion is also done here in this paper.
