   PRESENT AND FUTURE TRENDS IN POWER ELECTRONIC CONVERTERS
By J.D. Van Wyk [View]
[Download]

Abstract: The development from the past to the present is utilised to defme the process of development of the various aspects of the technology of electronic power conversion. The present state of the art is reviewed, without reference to detail, but rather with attention to generic issues. This evaluation reviews power electronic devices, components, packaging and cooling, as well as present power electronic converter technology, including snubbers, resonant converters, resonant transition converters, current fed, voltage fed, direct and minimum converters. The present trends are identified and particularly related to packaging and cooling technology, manufacturing technology, environmental impact technology and converter electromagnetics. The future possibilities of electronic power converter technology is particularly discussed in relation to packaging and cooling, environmental impact - including materials and EMIlEMC - manufacturing technology and converter electromagnetics.

   NEW TRENDS IN ACTIVE FILTERS
By H. Akagi [View]
[Download]

Abstract: Since their basic compensation principles were proposed in the 1970's, active filters have been studied by many researchers and engineers aiming to put them into practical applications. At present, shunt active filters for harmonic compensation, flicker compensation or voltage regulation have been put on a commercial base in Japan, and their rating or capacity has ranged from 50kVA to 50MVA. In near future, the term of active filters will cover a much wider sense than that of active filters in the 1970's did. The function of active filters will be expanded from voltage flicker compensation or voltage regulation into power quality improvement for power distribution systems as the capacity of active filters becomes larger. This paper describes present states of the active filters based on state-of-the-art power electronics technology, and their future prospects toward the 21st century, including the personal view and expectation of the author.
