Direct generation of alternating current at high voltages
Journal of the Institution of Electrical Engineers, 1929The authors begin by pointing out, with the help of a mechanical analogy, the true place which the alternating current transformer takes in the group of plant considered to-day to be standard for the generation, transmission and distribution of electric power on a large scale.They propose the use of high-voltage alternators and the partial abolition of

High Direct Voltages and Currents
2019High direct (DC) voltages and currents are becoming increasingly important because of the increasing number of high voltage direct current (HVDC) transmission systems worldwide. Numerous other application fields exist in physics and technology, and DC voltages are also needed to generate impulse voltages and currents.
