Scientists from Bangalore-based Indian Institute of Science (iisc) have developed an inverter, which could help power refrigerators storing life-saving drugs and vaccines in rural areas. Due to frequent power cuts, the medicines, which are rarely available in the rural places, go bad. Consequently, instead of having beneficial effects, they can lead to fatal health complications.

While conventional inverters are widely used to power many gadgets during power cuts, refrigerators do not benefit from these, both in rural and urban areas. This is because, unlike most other electrical appliances, refrigerator's power and voltage requirements vary during the
