A 5 kV, 1.5 MW, variable DC source

A description is given of a 5 kV, 300 A, variable DC source. This source will be used to determine the short-circuit impedances of HVDC (high-voltage direct-current) links. The converter is composed of four eight-thyristor bridges connected in series in a 24-pulse arrangement. The triggering pulses are transmitted to the thyristors by fibre-optic cables.<<ETX>>
