Abstract
A voltage source converter includes two half bridges each having two current valves connected in series to be connected to opposite poles of a DC source/load. A gate drive unit controls a semiconductor device of a current valve. An arrangement carries out voltage measurements for providing a value of DC voltage between the opposite poles. A voltage divider connected across the two current valves measures DC voltage between opposite poles and each voltage divider has an output connected to processing parts delivering a digital signal representing a value of the DC voltage between the poles. Two gate drive units send a digital signal to a calculating unit to carry out a quality estimation of the digital signals and to calculate a DC voltage value from the signals while giving each signal a weight corresponding to the quality value adhered thereto and then forming a weighted average value.
