An electric load damper assembly, comprising: a synchronous generator operable to provide a plurality of phases (A-C) of electrical output in response to a mechanical input from a rotating shaft; an electric load damper including a phase leg (50a-f) for each of the plurality of phases, each phase leg comprising: a resistive load; and at least one solid state switch (56, 58); and a controller operable to receive a signal indicative of a rotational speed oscillation of the synchronous generator, the controller being further operable to selectively reduce a torsional oscillation of the shaft by diverting electrical current from the synchronous generator through the resistive load of each of the plurality of phases in response to the signal exceeding a predefined rotational speed oscillation threshold, and characterised in that: each phase leg further comprises a snubber; the at least one solid state switch is connected in parallel with the snubber, the at least one solid state switch and snubber being collectively connected in series with the resistive load; and the controller only turns the at least one solid state switch (56, 58) ON during positive half cycles of the signal, during negative periods of the signal the switches (56, 58) being OFF; and the controller stops turning the at least one solid state switch ON during positive half cycles of the signal when the oscillations no longer exceed the predefined rotational speed oscillation threshold. a synchronous generator operable to provide a plurality of phases (A-C) of electrical output in response to a mechanical input from a rotating shaft; an electric load damper including a phase leg (50a-f) for each of the plurality of phases, each phase leg comprising: a resistive load; and at least one solid state switch (56, 58); and a resistive load; and at least one solid state switch (56, 58); and a controller operable to receive a signal indicative of a rotational speed oscillation of the synchronous generator, the controller being further operable to selectively reduce a torsional oscillation of the shaft by diverting electrical current from the synchronous generator through the resistive load of each of the plurality of phases in response to the signal exceeding a predefined rotational speed oscillation threshold, and characterised in that: each phase leg further comprises a snubber; the at least one solid state switch is connected in parallel with the snubber, the at least one solid state switch and snubber being collectively connected in series with the resistive load; and the controller only turns the at least one solid state switch (56, 58) ON during positive half cycles of the signal, during negative periods of the signal the switches (56, 58) being OFF; and the controller stops turning the at least one solid state switch ON during positive half cycles of the signal when the oscillations no longer exceed the predefined rotational speed oscillation threshold. each phase leg further comprises a snubber; the at least one solid state switch is connected in parallel with the snubber, the at least one solid state switch and snubber being collectively connected in series with the resistive load; and the controller only turns the at least one solid state switch (56, 58) ON during positive half cycles of the signal, during negative periods of the signal the switches (56, 58) being OFF; and the controller stops turning the at least one solid state switch ON during positive half cycles of the signal when the oscillations no longer exceed the predefined rotational speed oscillation threshold.
