2. Spain-Morocco interconnection - Wikipedia

   en.wikipedia.org/wiki/Spain-Morocco_interconnection

   The Spain-Morocco interconnection includes two 400 kV lines, commissioned in 1997 and 2006 that have a combined power of 1,400 MW and consisting of seven cables: three for each circuit, plus one for reserve. [3]

3. List of HVDC projects - Wikipedia

   en.wikipedia.org/wiki/List_of_HVDC_projects

   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 ...

4. Cometa (HVDC) - Wikipedia

   en.wikipedia.org/wiki/Cometa_(HVDC)

   COMETA (abbreviation for COnexión MEditerránea Transporte Alta tensión; also known as the Majorca–Valencia interconnector and the Romulus project) is an undersea electric power transmission system between mainland Spain and the island of Majorca. It connects Morvedre near Valencia and Santa Ponsa near Palma de Mallorca.

5. Mains electricity by country - Wikipedia

   en.wikipedia.org/wiki/Mains_electricity_by_country

   Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some ...

6. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   Certain specialized circuits can also be considered power converters, such as the flyback transformer subsystem powering a CRT, generating high voltage at approximately 15 kHz. Consumer electronics usually include an AC adapter (a type of power supply ) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips.

7. HVDC converter - Wikipedia

   en.wikipedia.org/wiki/HVDC_converter

   In such converters, the polarity of DC voltage is usually fixed and the DC voltage, being smoothed by a large capacitance, can be considered constant. For this reason, an HVDC converter using IGBTs is usually referred to as a voltage-source converter (or voltage-sourced converter [26]). The additional controllability gives many advantages ...
