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.

After reaching Chennai:

The IIT Madras campus is located on the Sardar Patel Road, halfway between the Raj Bhavan and the Adyar bus terminus, i.e. about 12 km from Chennai Central. The other landmarks are the Guindy Snake Park adjacent to the IIT main gate and the Central Leather Research Institute (CLRI) campus lying opposite ours. The travel time from the airport, railway stations or Koyambedu bus terminus is approximately 45 minutes.

After reaching IIT Madras:

Once you reach the In-gate, there are buses to Gajendra Circle (near the administrative block and Central Library), the academic zone, and the hostels (they are around 3.8 km from the main gate) almost every 15 minutes from 6 A.M. to 10 P.M. The following are the ways to reach IIT from railway stations, airport, and bus terminus.

The accommodation will be provided on payment basis.
