The Alternating Evolution of DC Power Transmission [Historical]
IEEE Industrial Electronics Magazine, 2013After more than one century of evolution of alternating current (ac) and thanks to the competitive costs of alternators and transformers, today a great majority of electricity is produced, transmitted, and distributed worldwide by means of ac polyphase systems [1], [2].

An integrated tri-mode DC-DC converter with segmented power devices and power transmission gate
2015 IEEE International Conference on Electron Devices and Solid-State Circuits (EDSSC), 2015An integrated high efficiency tri-mode DC-DC converter that can operate in buck, boost and buck-boost configurations is presented. A power transmission gate is implemented in the tri-mode converter as the high side driver of the H-bridge output stage to extend the range of the output voltage to be lower than 1.5 V.

Why DC for Long-Range Power Transmission
The Physics Teacher, 2002The case for dc versus ac power transmission is reviewed. It is concluded that for long transmission distances, i.e. more than 800 km (500 miles), dc transmission is cheaper and probably more reliable. The 1.0-MV Pacific Intertie is cited as an example of a modem efficient dc system.

Stability improvement of power system by simultaneous AC–DC power transmission
Electric Power Systems Research, 2008Abstract This paper presents a concept of improving the transient stability of power system by simultaneous AC–DC power transmission through a transmission line. A double circuit long transmission line is converted to simultaneous AC–DC line for feasibility study. Loss of synchronism is prevented by quickly producing sufficient decelerating energy to

The peculiarities of high-voltage dc power transmission
IEEE Spectrum, 1966The cost of a basic dc line is always less than that of an ac line. For submarine installations the difference is particularly pronounced; for underground cables, the difference is somewhat smaller. For overhead transmission on land, many studies show that a dc line generally costs about one third less than an ac line of the same capacity.

Long-distance DC electrical power transmission
IEEE Electrical Insulation Magazine, 2013Transmission and/or distribution systems are needed to transport electrical power from its generation site to the user locations. This paper reviews major DC power transmission technologies, concentrating on systems that are capable of long-distance transmission. Special attention is paid to lifetime models and the safe use of DC insulation systems.
