Preamble

Grid-connected inverters are used between local electrical power generators. To inject electrical power efficiently and safely into the grid, grid-connected inverters must accurately match the voltage and phase of the grid sine wave AC waveform. For applications such as microgrid integration with the power grid, the voltage at the output terminal is desired to be sinusoidal with adjustable magnitude and frequency. This is achieved by employing a DC to AC inverter that accepts DC voltage as input and generates the desired AC as output voltage. The output of the inverter contains harmonics and needs to be filtered. The filtered signals are connected to the transformer to isolate the system from the grid. The inverter, filter, and transformer form the essential electrical power conversion stages. The course will be concentrated on three-phase grid-connected inverters.

This workshop will be a three-day workshop. The morning sessions will be theoretical. The afternoon session of Day 1 will introduce different aspects of designing a hardware setup and introduction to DSP. Day 2- afternoon session is for the simulation. Simulations are planned with tools like MATLAB. (For participants who do not have access to the software, virtual access facility to the software at IITM Lab shall be provided). Day 3-afternoon session of the workshop will be DSP code implementation and hardware demonstration. The real-time simulation of a grid-connected inverter using Texas 28379D DSP shall be included in the course.

The Venue


Electrical Science Block

IIT Madras

Our department was established in 1959. We currently have about 685 research scholars, 72 faculty members, 43 other faculty members, 30 staff members, and 4 post-doctoral fellows with us.

We perform a variety of research work from absolute fundamentals to component design to system integration to deployment/commercialization. We have strong industry interaction and have been involved in the development of state-of-art products. We house extensive fabrication, calibration, and testing facilities for carrying out academic projects, sponsored research, and consultancy projects.

IIT Madras is a residential institute that occupies a 2.5 km² (617 acres) campus that was formerly part of the adjoining Guindy National Park. The main entrance of IIT Madras is on Sardar Patel Road, flanked by the residential districts of Adyar and Velachery. The campus is close to the Raj Bhavan, the official seat of the Governor of Tamil Nadu.

Much of the campus is a protected forest, carved out of the Guindy National Park, home to many animals that are not commonly seen in a busy city like Chennai. The campus has the pride of having one of the most elegant antelopes in the world - the Blackbuck. The campus is also home to large numbers of chital (spotted deer), bonnet macaque, monkeys, and other rare wildlife. There are a lot of other smaller and exquisite life forms that play a major role in the biodiversity of the campus. The IIT campus has about 300 species of trees and plants with quite a large number of native wild species, which are unique to the tropical, dry evergreen vegetation.
