Abstract

A circuit arrangement for precharging the capacitor connected to the output of a line-commutated power converter is described, where an element which limits the charging current of the capacitor to a level which is largely independent of the charging voltage is connected between a direct voltage output of the power converter and the respective terminal of the capacitor.
