Abstract
The progress in light emitting diodes (LEDs), especially in producing ultraviolet light, leads to new applications in medical science and in the area of disinfection. Biological investigations show a greater effectiveness when the ultraviolet light is pulsed. Therefore, converters which enable a fast turn-on and turn-off of the light emitting diodes are necessary. Several concepts to improve the possibility to supply switched loads are shown, and the equations for linear and two-level control are derived from the model equations. Dimensioning hints are given.
