Abstract
The present invention relates to a driver circuit for a flash tube. The driver circuit comprises a first and a second output for an electronic flash tube, a capacitor, an inductor and a switch. The inductor and the switch being connected in series with the first and a second output across the capacitor. A component which only allows current flow in one direction connected across the first and the second output and the inductor, with a polarity opposite to a direction of energy supply from the capacitor to the first output. The driver circuit further comprises a controller for controlling the switch. The controller comprises receiving means for receiving parameters related to desired flash characteristics. The controller being configured to control said switch based on said parameters to obtain said desired flash characteristics.
