Abstract: A power supply assembly including a primary source connection, a secondary source connection, a load connection, a primary current supply route, a supply switch system, and a converter system. The supply switch system is electrically located in the primary current supply route, and adapted for disconnecting the primary source connection from the load connection, the supply switch system including a plurality of supply switch units connected in parallel, each of the supply switch units including a controllable semiconductor switch. The power supply assembly includes a series impedance system having at least one series impedance member, and adapted to provide a balancing voltage drop for each of the parallel connected supply switch units of the supply switch system, wherein the balancing voltage drop is in series with a corresponding supply switch unit.

Abstract: A unifying and automated access and archiving method and system that permits unification, in one single login procedure, access to all networks and Web portals, and, at the same time, automatic downloading of relevant documents made available in the Web, i.e., by suppliers and Public Administration. The method and system allows creation of a home archive to store all documents, data and contents of interest, both captured from the sources at Web portals and from sharing actions with other users. Documents are organized and stored on the basis of predefined logical criteria so being stored and made available for prompt research and eventual sharing.
