Abstract

Cet article traite des onduleurs multi-niveaux asym ´etriques a cellule en s´erie. Ces onduleurs sont constitu´es de cellules onduleur, connect´ees en s´erie et dont les tensions d’entr´ee sont diff´erentes. La condition d’uniformit´e de ces onduleurs et une condition plus restrictive permettant de minimiser les commutations sont ´etablies. Ces 2 conditions facilitent le choix des tensions d’alimentations des cellules. A partir d’une approche g´eom´etrique, une strat´egie de commande adapt´ee a la minimisation des commutations et donc des pertes associ´ees est propos´ee, ainsi qu’une approche digitale pour la commande des onduleurs multi-niveaux. Les r´esultats pr´esent´es sont g´en´eraux.

Mixed boundary condition

In mathematics, a mixed boundary condition for a partial differential equation defines a boundary value problem in which the solution of the given equation is required to satisfy different boundary conditions on disjoint parts of the boundary of the domain where the condition is stated. Precisely, in a mixed boundary value problem, the solution is required to satisfy a Dirichlet or a Neumann boundary condition in a mutually exclusive way on disjoint parts of the boundary.

History of the Internet

The history of the Internet has its origin in information theory and the efforts of scientists and engineers to build and interconnect computer networks. The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.

Art Deco

Art Deco, short for the French Arts Décoratifs, and sometimes referred to simply as Deco, is a style of visual arts, architecture, and product design, that first appeared in France in the 1910s (just before World War I), and flourished in the United States and Europe during the 1920s to early 1930s. Through styling and design of the exterior and interior of anything from large structures to small objects, including how people look (clothing, fashion and jewelry), Art Deco has influenced bridges, buildings (from skyscrapers to cinemas), ships, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects like radios and vacuum cleaners.
