Abstract: In a method for control of a converter for conversion of dc voltage into ac voltage or dc voltage and vice versa, in which an output of the converter may alternatively be connected to a positive pole, a negative pole or a center of a dc voltage side of the converter in the form of different so-called main states, there is carried out, when changing between main states via a so-called minor commutation loop, an extra sequence in the form of a delayed turn-on of semiconductor elements in one unit of the converter relative to semiconductor elements in another unit in a pair of units of the converter.

Abstract: A device for supervising different positions of a valve of a high voltage converter station located on a high voltage potential level comprises members arranged on a high voltage potential level and adapted to detect function parameters of the valve on a high voltage potential level and send values detected thereby to first control units for controlling the semiconductor components of the valve. The first control units have devices for processing the detected values and the first control units are adapted to utilize light conductors running back therefrom to a valve control unit for sending data resulting from the processing to an arrangement for supervising the valve located on a low potential level.

Abstract: An apparatus and method for communication between low potential level and a valve of a high voltage converter station located on high voltage potential level is provided. The apparatus comprises means adapted to send serial messages on light conductors between a valve control unit and a first control unit for controlling semiconductor components of the valve of turn-on type on high voltage potential level in periods of time when the respective light conductor is free from signals associated with a change in the conducting state of the semiconductor component, such as turn-on and/or indications signals.

Abstract: The invention relates to a method for supervising the functioning of a plurality of valve units, a system for performing the method, a control unit and a control assembly for cooperation with the control unit. Each valve unit in the system comprises a semiconductor element (THY1-THYN) and a control unit for controlling the semiconductor element. The control unit comprises a trigger order input for receiving a trigger order (FP), an indication output for emitting a first indication signal (TP) and a trigger signal output (100) for emitting a trigger signal to the semiconductor element. The method comprises the steps: detecting a positive forward voltage (U.sub.T) across the semiconductor valve, generating a first indication signal (IP) when the forward voltage (U.sub.T) exceeds a first threshold value (U.sub.1), generating a trigger signal upon detected receival of the triggering order signal (FP), and the step: generating a second indication signal (SSTP) when the forward voltage (U.sub.T) exceeds a second threshold value (U.sub.2).
