Abstract :
As we prepare to enter the 21st century we stand on the threshold of a power electronics revolution. The last 50 years have seen the growtll of power conversion to the point at which today about 15% of tile electric power produced undergoes some form of electronic conversion. However, most of this occurs at the ʹconsumer endʹ of the supply chain from battery chargers to locomotives. Although HVDC transmission has exploited line-commutated power electronics for the past three decades, it is the 1990s which have witnessed the commissioning ofselfcommutated power electronics at the transmission level. Developments in semiconductors and their packaging technology will drive power electronics into distribution applications as device efficiency and reliability increases whilst the cost of the switched megawatt falls. The key semiconductors enabling this predicted transition are reviewed and the anticipated demands of system builders on device suppliers discussed.
