IIT-Madras power system promises reduced blackouts

The Indian Institute of Technology Madras (IIT-Madras) revealed that it has developed a system that could potentially reduce adverse effects of power outages.

The 'uninterrupted direct current' promises that electricity will still be available from the grid to power basic appliances such as fans, TVs and lights, even mobile phone chargers, despite excess in demand. This can be achieved by running a low-power direct current (DC) line to homes from every substation, which will feed into a separate meter ('re' for unit of measurement) and onto devices that require minimal power. Regular alternating current (AC) power would then be directed to other appliances. The challenges for the implementation of this technology include switching electronics to work at 48VDC as well as standardisation of direct current.

The IIT-Madras design team is led by Ashok Jhunjhunwala, professor of electrical engineering, along with director Bhaskar Ramamurthi. EE Times India is in touch with Prof. Jhunjhunwala and will provide a comprehensive discussion of the technology as the information becomes available.
