Abstract
A generator for a flash device includes at least a first capacitor bank, which includes at least one capacitor of a first type and at least a second capacitor bank, which includes at least one capacitor of a second type. The first capacitor bank is connectable to a charger via a first switch and the second capacitor bank is connectable to a charger via a second switch. The generator is configured to individually control the first switch and the second switch so that the first capacitor bank and the second capacitor bank can be individually charged to the same or different voltages. Since the first capacitor bank and the second capacitor bank can be simultaneously discharged, it is possible to achieve a desired energy level and color temperature from a flash device connected to the generator.
