| Abstract |
Power electronics and variable frequency
drives have gone through rapid technological
advancement during the last four decades, and
recently, their applications are fast expanding in
industrial, commercial, residential, military and
utility environments. In the global industrial
automation, energy conservation and environmental
pollution control trends of the 216 century, the
widespread impact of power electronics and drives
will be inevitable. In this paper, recent advances of
power semiconductor devices, converters, variable
frequenq drives, advanced control and estimation
techniques will be reviewed The trends of individual
technology will be highlighted wherever possible.
Finally, a few selected recent projects will be
reviewed. |
