Sudhir Kumar Sinha was with the faculty of Indian Institute of Science (IISc), Bangalore (India) for over 30 years. He retired from the Centre for Electronics Design and Technology (CEDT) in 2011. His main areas of interest are Power Electronics, Fault-tolerant and Safety-Critical Systems and Embedded Systems.
During his tenure at IISc, Sinha worked on a number of research and development projects sponsored by Governmental agencies such as DIT, Indian Railways, National Tuberculosis Institute, DRDO and BHEL. In addition, many projects have been carried out with funding from multinationals and SMEs such as Motorola, Freescale, Tejas Networks, McML, Impact Solutions, etc. Some of the major projects completed were:
- Multiphase chopper controller with regenerative braking capability for DC Electric Multiple Unit Trains.
- Train load simulator with programmable load profile upto 35 kW.
- ‘Hardware-in-loop’ computer simulation of traction drive.
- High speed drive for mining elevators – design, development, deployment and testing of 600KW high speed drive system for the mining elevators of the Moonidih coal mines (Jharia) of the BCCL, India.
- Battery operated variable voltage inverter to power conventional X-Ray units – 7.5 kW inverter was built and commissioned as a mobile unit of National Tuberculosis Institute, Bangalore.
- Real time controller for the run out table of hot strips mills – this multi-disciplinary study was supported by Tata Steel and conducted in collaboration with the Dept. of Metallurgy (now Materials) at IISc.
- Fault-tolerant data driven distributed architecture for future generation avionics – study was sponsored by ADE (now classified).
- State of charge estimator for lead acid batteries
- Light weight electric vehicle
- Digital receiver for Ooty radio telescope – digital instrumentation system developed to enhance the capability of the Ooty Radio Telescope. The work was carried out in collaboration with the Raman Research Institute, Bangalore.
- Electronic interlocking for railway signalling – an electronic interlocking system intended for 4-line stations of the Indian Railways was designed and implemented entirely in hardware. The system meets the stringent safety standard SIL level 4.
- Wireless Biometric authentication – to remotely authenticate security guards and other individuals.
Sinha obtained B.Sc.(Engg) degree from Patna University in 1967 and ME and Ph.D degrees from Indian Institute of Science, Bangalore in 1979 and 1985 respectively.
