Abstract

Der Fortschritt in der Entwicklung von liehtemittierenden Dioden (LED) im UV-Bereich führt zu immer neuen Anwendungsgebieten in der Elektromedizin (z. B. Blaulichttherapie, Pilz­ und Milbenbekämpfung) und in der Desinfektion (z. B. von Oberflächen und Flüssigkeiten). Wirkungsvoll sind dabei steile Stromflanken. Die Aufgabe, Topologien fiir Gleichspannungswandler zu finden die Strompulse mit hoher Flankensteilheit liefern, wird erfindungsgemäß dadurch bewerkstelligt, dass der parallel zu den Ausgangsklemmen liegende Kondensator entfernt wird und statt dessen ein aktiver Schalter (S2) oder mindestens zwei in Serie geschaltete, gleichzeitig angesteuerte aktive Schalter geschaltet wird/werden, der oder die den Strom der Induktivität (L) im eingeschalteten Zustand führen kann/ können.The progress in the development of UV-emitting LEDs has led to ever new applications in the field of electromedicine (eg blue light therapy, fungus and mite control) and in disinfection (eg of surfaces and liquids). Effective are steep current edges. The task of finding topologies for DC-DC converters which deliver current pulses with high edge steepness is accomplished according to the invention by removing the capacitor which is connected in parallel with the output terminals and instead by an active switch (S2) or at least two series-connected, simultaneously activated active switches is / are switched, the or can cause the current of the inductance (L) in the ON state / can.
