Electric power transmission through interconnectors using high-voltage direct-current (HVDC) involves usually two converter stations and a transmission line. Generally overhead lines are used, but an important class of HVDC projects use submarine power cables. A back-to-back station has no transmission line and joins two separate AC grids at a single point. Historical HVDC systems used the Thury system of motor-generators but these have all been made obsolete by later developments such as mercury-arc valves (now also obsolete), thyristors, and IGBT power transistors.

## Legend

Converter technology:
* Thury = Series-connected generators as designed by René Thury
* Merc = Mercury-arc valve rectifier and inverter
* Thyr = Thyristor rectifier and inverter
* IGBT = Insulated gate bipolar transistor
* BIGT = Bi-mode insulated gate transistor
* IEGT = Injection enhanced gate transistor
