Abstract
A voltage converter having a voltage intermediate circuit and an invertor connected to the output of the voltage intermediate circuit. The invertor produces a three-phase AC voltage at its output and is connected to the output terminals of the voltage converter by a filter arrangement. The filter arrangement includes a filter inductor connected in series with the output terminal and the filter capacitor connected between the output terminal and a common capacitor star point. Attenuation of the DC system is achieved by having the capacitor star point connected to the voltage intermediate circuit by way of an RC element having a capacitor and a resistor.
