Development of Switching Power Supply for Deuterium Lamp [Copy link]

Deuterium lamp is the most ideal ultraviolet light source for spectrophotometer, with continuous spectrum and wavelength of 190nm~400nm. The traditional deuterium lamp power supply is a linear power supply, which is characterized by relatively stable characteristics, but its shortcomings are difficult to overcome: first, it is difficult to adapt to the international civil universal voltage, that is, the automatic conversion between 110V and 220V AC input; second, the transformer is bulky and the constant current source has large losses. Switching power supply can avoid the above shortcomings. At present, switching power supply for deuterium lamp has also appeared, but its filament, trigger, lighting and other power supply groups are independent, the cost is high, and in practical applications, it is of little significance. This article introduces a deuterium lamp power supply composed of only one switching power supply module, which is low in cost and reliable in performance.
