The Al-Fadhili back-to-back HVDC station is a back-to-back HVDC connection between Saudi Arabia, whose grid operates at 60 Hz, and its neighbouring Gulf states which have 50 Hz grids. [1] The station is located in Saudi Arabia, approximately 100 km north-west of Dammam, but was built for and owned by Gulf Cooperation Council Interconnection ...
The Western HVDC Link is a high-voltage direct current (HVDC) undersea electrical link in the United Kingdom, between Hunterston in Western Scotland and Flintshire Bridge (Connah's Quay) in North Wales, routed to the west of the Isle of Man. [2] It has a transmission capacity of 2,250 MW and became fully operational in 2019.
Its schematic can be seen in figure 1. It is an inverting converter, so the output voltage is negative with respect to the input voltage. The main advantage of this converter is the continuous currents at the input and output of the converter. The main disadvantage is the high current stress on the switch.

Protective relay. v. t. e. An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. [ 1] It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains:
Recloser. Protective relay. v. t. e. In electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current.
In electronics, a digital-to-analog converter ( DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal. An analog-to-digital converter (ADC) performs the reverse function. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including ...
The single-ended primary-inductor converter (SEPIC) is a type of DC/DC converter that allows the electrical potential at its output to be greater than, less than, or equal to that at its input. The output of the SEPIC is controlled by the duty cycle of the electronic switch (S1).
Power rating. 2 x 500 MW. DC voltage. 205 kV (each pole) No. of poles. 2. The Chandrapur back-to-back HVDC station is a back-to-back HVDC connection between the western and southern regions in India, located close to the city of Chandrapur. Its main purpose is to export power from the Chandrapur Super Thermal Power Station to the southern ...
