    • An electrical inverter with controllable output voltage comprises a three-phase self-commutated inverter bridge which is supplied from a d.c. voltage source. A reference signal generator generates a three-phase binary reference signal for controlling the shape of the curve of the output voltage of the inverter. This signal is modulated or mixed in a mixing stage with a binary pulse train having a controllable pulse-width ratio and a relatively high frequency. The output signal from the mixing stage is supplied to the inverter bridge in such a way that the output voltage of the inverter bridge corresponds to the product of the reference signal and the pulse train.

    • In a method for damping power oscillations in a transmission line, at least one first angular-frequency signal is generated, representing a first angular frequency which is given by a prior knowledge of oscillation frequencies expected in the power system, and a first phase-reference signal is formed as the time integral of the angular-frequency signal. A power quantity in the transmission line characterizing the power is sensed and a first estimated power quantity is formed, representing for an oscillation of the first angular frequency, its amplitude and phase position relative to the first phase-reference signal. A first damping signal is formed with an amplitude dependent on the amplitude of the first estimated power quantity and with a first phase shift in relation to the phase position thereof, and the first damping signal is supplied to an actuator for influencing the power transmitted in the transmission line.
