Abstract
Converters () for supplying pulsed power to light sources () comprise switching parts () and controlling parts () for adapting switching parameters of the switching parts () for improving a performance. The switching part () may comprise first/second switches () that are in first/second modes during a first time interval of a cycle and vice versa during a second time intervals of a cycle. A group of cycles results in a pulse of the pulsed power. A switching parameter such as the first time interval of a first cycle may be shortened to reduce overshoot. A switching parameter such as the second time interval of the first cycle may be shortened or lengthened. A switching parameter such as the second time interval of a last cycle may be lengthened or shortened to reduce overshoot. A third switch () for switching the light source () is activated and de-activated delayedly to improve transient behavior.
