ABSTRACT:
A process and apparatus for charging a capacitor, particularly for flash guns with a fast flash series, so as to achieve a short charging time while avoiding a high charging current pulse, the charging current during the course of the charging being regulated to a value which at least approaches a constant. The time constant of the charging circuit is altered during the charging process by a controlled resistance arrangement which is controlled in dependence upon the charging voltage of the capacitor.
