• Power Electronics has been gaining relevance in
countless fi elds throughout industry, defence,
transport, public buildings, communications,
computing, home automation and electromedical equipment. Although usually unnoticed,
due to its subsidiary role of supplying energy to
electrical equipment and systems, its applications
and implantation are continuously growing.
The power range is very wide, covering from
over fi ve thousand megawatts in High Voltage
DC Transmission to a few tenths of a watt in
micro-power converters for mobile telephones
and personal electro-medical devices. Its
multidisciplinary character and universality
makes of power electronics a technological
synergic vortex where semiconductor physics,
electrical engineering, thermal management,
control theory, industry communications,
transport and most industrial disciplines are
brought together. This paper, fi rst of two, covers
general aspects of Power Electronics and its
applications in the high power range
