Project Summary
As the world is paying attention on the solar system for electricity generation multilevel inverters are also getting attention due to advancement in power electronics. This project introduces a standalone multi solar energy harvesting system with reduced device count multilevel inverter by implementing FPGA. The system consist solar module or panels, DC-DC converter, reduced device count multilevel inverter. Standalone multi solar energy harvesting system is a utility power alternate. The solar light energy is harvesting by using solar panels and converted into electrical energy. There is P&O maximum power point tracking technique is used, which is used to indirectly increase the efficiency of PV panels. The DC-DC converter steps down and regulate the magnitude of the harvested voltage and supplied to the reduced device count multilevel inverter. DC voltage can be converted into AC voltage by using RDC MLI and supplied to load. The FPGA ( field programmable gate array) is used for switching control of power semiconductor switches (IGBTs) in RDC MLI.
Project Objectives
The objectives of this project are:
- Generate the code of programing language for seven-level cascaded H-bridge MLI with reduced device count by FPGA.
- Using the perturb and observe method (P&O) for MPPT to improve the efficiency of the standalone solar energy harvesting system.
- Develop the standalone multi solar energy harvesting system with RDC MLI by implementing FPGA.
- Performance analysis of the hardware.
Project Implementation Method
The focus of this project is to construct a compact and affordable standalone multi solar energy harvesting system with reduced device count multilevel inverter by implementing FPGA. Many lifestyles and applications require standalone multi solar energy harvesting system with RDC MLI due to insufficiency or absence of any kind of energy grid. These involve remote settlements, household, solar cars, aircraft, hospitals, industries, agriculture, educational institutes, and many more.
