(a) Two three-phase, 400kV (rms), 50Hz, AC networks are connected together via a current-source HVDC link made up of a three-phase, 12-pulse full-wave thyristor rectifier and a three-phase, 12-pulse full-wave thyristor inverter. (i) Draw the circuit diagram for this system and explain, for the rectifier stage, how the firing delay angle may be used to control the average DC voltage. (ii) Explain the main advantages of HVDC transmission compared to AC transmission. (b) An H-Bridge converter is to be used...
