CONVERTER FOR SUPPLYING PULSED POWER TO LIGHT SOURCE |
摘要 |
Converters (1) for supplying pulsed power to light sources (8) comprise switching parts (2) and controlling parts (3) for adapting switching parameters of the switching parts (2) for improving a performance. The switching part (2) may comprise first/second switches (41, 42) 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 (93) for switching the light source (8) is activated and de-activated delayedly to improve transient behavior.
