In its endeavour to support R&D for Industrial Applications and to address the needs of the core industrial sectors the division supports a number of national collaborative projects at Research/Academic Institutions and Industries, Some examples of completed and ongoing projects are the following:
National Mission of Power Electronics Technology (NaMPET)
NaMPET as a mission programme was launched in November, 2004 as first large initiative by DeitY in the area of power electronics for facilitating research, development, deployment and commercialisation of power electronics technology by enhancing the indigenous R&D expertise and infrastructure in the country. As part of NaMPET phase-I programme, power electronics infrastructure facilities have been built at CDAC, Thiruvananthapuram and Labs in different areas of power electronics were created at 11 premier academic institutes including IITs (Bombay, Kanpur, Kharagpur, Delhi), IISc Bangalore, Anna University Chennai, BESU Kolkata, NITs (Trichy, Rourkela, Kotayam) and BIT Ranchi. Some of the advanced power electronics technologies developed under NaMPET are:
- Full Spectrum Simulator, a tool for designing, operating and understanding complex systems encountered in power systems.
- Matrix Converteris as an “all silicon” solution for AC-AC conversion.
- Universal Front End Converters for Micro Generators to convert the power output of micro generators into usable voltage at a particular frequency.
- IGBT Gate Drivers which are highly versatile single channel/ dual channel gate drivers for IGBTs up to 1700 Volts and 1200 A ratings with electrical or fibre optics interface.
- Hall Effect based Current Sensors which are the major components for DC/AC current measurements in industrial applications.
NaMPET has served as a platform for power electronics experts from industries, R&D and academic institutes to come together and take up joint development activities. Under NaMPET, a number of awareness creation programmes like Short Term Courses, National Annual Workshops and Seminars have been conducted with support from all the participating agencies, which has created a notable impact in attracting power electronics professional and students in the country. These activities have helped in enhancing the power electronics technology base and capabilities in the country.
User Ministries like Indian Railways and Ministry of Power have joined hands with NaMPET and part funded development of Vehicle Control Unit, Train Communication Network, Auxiliary Converter, STATCOM for neutral current compensation at IT Parks etc.
A typical example of joint funded 2 X 500 KVA STATCOM project implemented at Techno Park, Trivandrum as shown below:
