Automobiles Electrifying uses for power electronics in auto sector Our Bureau
Hyderabad , Sept. 23 THE evolution of power electronics promises to revolutionise the way car-makers design cars and manufacturers of home appliances reshape their products with increased inefficiency. According to Prof Alfio Consoli of University of Catania (Italy), the number of devices based on power is rapidly increasing. ``Cars will have fuel cells in them to meet the energy needs within cars,'' he added. ``To adopt this energy, you need power electronics. It has got a wide ranging application in the automotive field.'' Prof Consoli was in the city to deliver the thirteenth Faraday Memorial Lecture - 2003 on `Advanced Control Techniques in Modern Electrical Drives', organised by the Hyderabad section of Institute of Electrical and Electronics Engineers, Inc. Prof Consoli, who authored more than 150 technical papers, co-authored the book `Modern Electric Drives' said the role of electrical drives is very essential in a digital control world where Internet-enabled appliances, ultra-precise manufacturing systems, efficient hybrid vehicles are expected to flood the market. Power electronics — the marriage of power and electronics, will also have bearing on both low-end applications like home appliances and high-end applications in industrial sector. For one, the present-day home appliances consist of motors with 15-20 per cent efficiency. We can save sizeable amount of power by incorporating power electronics. Mostly, companies prefer to use low-efficient motors as cost of production is very low. Power electronics is also very useful in utility applications. ``We can reduce losses at the generator level itself by optimising their design, resulting in high efficiency and reduction in losses,'' Prof Consoli said. Mr J.A. Chowdary, Chairman of IEEE's Hyderabad section, said power electronics would pave the way for manufacture of intelligent white goods. ``In future, fridges will talk to one another,'' he said.
