A device for charging a charging capacity from an a.c. source via a transformer and rectifier by using at least one auxiliary capacitor for buffer-charging of the charging capacitor is disclosed. The charge of the capacitor is used for example for charging an accumulator and flashing a light source. Change of the capacity of the auxiliary capacitor makes it possible to regulate the charging characteristic of the charging capacitor in charging an accumulator and to regulate the flash character, i.e. intensity and flash frequency, in case of the charging capacitor being discharged through a flash bulb via a thyristor. |
