Parallel Operation of AC and DC Power Transmission
IEEE Transactions on Power Apparatus and Systems, 1965A preliminary account has already been given of the EHV composite ac-dc study initiated last year at the University of Wisconsin [1]. This paper presents additional results obtained in the study of parallel EHV ac-dc power transmission in a basic 2-machine equivalent system.

Evaluation of inductive coupling and RF-DC for Wireless Power Transmission
2012 Ninth International Conference on Wireless and Optical Communications Networks (WOCN), 2012The main reason for power loss during transmission and distribution is the resistance of wires used for grid and as growing all technologies in the world and nowadays one of the efforts is trying for transmitting power wirelessly. In this paper Wireless Power Transmission using inductive coupling is described in detail and its limitations are mentioned.

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.

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 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].

EFFECTIVE INDUCTIVE POWER TRANSMISSION TECHNIQUE WITH EFFICIENT DC TO DC CONVERTER FOR EVEHICLE
2023The development of the earliest electric automobiles, also known as E-vehicles, can be traced all the way back to the middle of the nineteenth century. One of the most significant benefits of driving an electric vehicle is the decrease in the total quantity of emissions produced.

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.
