Title: PRECHARGING CIRCUIT FOR A CAPACITOR CONNECTED TO THE OUTPUT OF A LINE-COMMUTATED POWER CONVERTER
Abstract:
The invention relates to a circuit for precharging a capacitor connected to the output of a line-commutated power converter. According to the invention an element is connected between a direct-voltage output of the power converter and the relevant connection of the capacitor which element limits the charging current of said capacitor to a value which is largely independent of the charging voltage.
