Power electronics belongs partly to power engineers and partly to electronics engineers. Power engineering is mainly concerned with generation , transmission, distribution and utilization of electric energy at high efficiency. Electronics engineering, on the other hand, is guided by distortionless production, transmission, and reception of data and signals of very low power level, of the order of a few watts, or milliwatts, without much consideration to the efficiency. In addition, apparatus associated with power engineering is based mainly on electromagnetic principles whereas the apparatus based on electronics engineering is based upon physical phenomena in vaccum, gases or vapours and semi conductors.
