There is described a device for connecting an electric power generator to an HVDC transmission system (190, 290, 390, 490, 590, 690, 790), the device comprising (a) a first unit for converting an AC output voltage from the electric power generator to a DC input voltage for the HVDC transmission system, the first unit comprising a transformer (120, 220, 321, 421, 520, 620, 720) and a full-bridge rectifier (110, 210, 310, 410, 510, 610, 710), and (b) a second unit for generating control voltages and/or control currents in the transformer and/or in the electric power generator, the second unit comprising a PWM full-bridge converter (130, 230, 331, 431, 530, 531, 630, 631, 730) adapted to receive the AC output voltage from the electric power generator or an AC voltage based on said AC output voltage. Furthermore, a system and a method are described. |
