Description

technical field [0001] The invention belongs to the technical field of drive power circuits, and in particular relates to a drive power circuit for pulse krypton lamps. Background technique [0002] At present, the traditional pulse krypton lamp drive circuit needs to use relay switch circuit, bridge rectifier circuit, IGBT and other circuits, resulting in the overall volume of the pulse krypton lamp drive circuit is relatively large, the system is complex, and the cost is high. In addition, because the traditional pulse krypton lamp drive power board requires corresponding krypton lamp drive boards for pulse krypton lamps of different specifications, the versatility and compatibility are also poor. [0003] Therefore, it is very necessary to design a driving power circuit for pulse krypton lamps that is small in size, simple in system, low in cost, easy to integrate, and strong in versatility and compatibility. [0004] For example, the Chinese patent literature with the a...
