AC Adjustable-Speed Drives with Electronic Power Converters-the Early Days

Power electronics quo vadis?

“…These metrics and details we have largely self-invented and projected. For example, it has been pointed out repeatedly that new topologies will not be driving the future development of power electronics [5][6][7] -and indeed history teaches us that the relevant topologies used in industry today are for the larger part older than most of us [8,9]. Very few "new" topologies have been adopted.…”

“…Unfortunately, up to the present there is still no work in existence that forms an encyclopaedic reference for the history of electronic energy processing. We have "snapshots" of the state of power electronics at certain instants in old text books that trace some historical development [12][13][14], while studies of certain aspects, such as application to electric machine control [8,15], or of some historical developments [9,16] provide some insight into when and where important ideas and technology advances came about. Two bibliographies cover the time from 1903 to 1966 [16,17], while the IEEE have published Special Issues of the Proceedings on aspects of power electronics during the last 50 years in 1967, 1988, 1994 and 2001 [18-21].…”

Collectively, these works [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] present references to literally thousands of publications, patents, inventions and applications. This enormous collection of references, when studied chronologically and in detail, will provide the missing encyclopaedic history of power electronics.…”

AC adjustable-speed drives at the millennium: how did we get here?

“…Such a work apparently does not exist at this time. However, acknowledgment must be given to several valuable papers and bibliographies contributed by specialists in this field that, collectively, tell much of the story of this important and fascinating technology development from an engineering perspective [4]- [8]. This paper is intended to build on these past works, focusing on the associated engineering issues.…”

Contribución al desarrollo de convertidores multinivel de alta tensión tolerantes a fallos

“…A pesar de la contribución que se ha hecho en el área de los Controles Tolerantes a Fallos, se ha prestado un poco menos de esfuerzo en el control del THD bajo fallos tolerantes. En la literatura podemos encontrar trabajos realizados como en [61], [62], que proponen un método pasado en la Eliminación Selectiva de Armónicos (SHE) con una o más faltas. El Control Tolerante a Fallo propuesto generará un sistema trifásico de tensiones equilibradas con el método convencional FPSC y disminuirá la THD manipulando la amplitud y el ángulo de los armónicos con el objeto descrito.…”
