Abstract: The present disclosure relates to a flash generator for providing power supply to a flash tube so that the flash tube rapidly provides a light output adapted to FP-sync, Flat Peak. The flash generator comprises a capacitor bank, an output and a switch configured to switch a current flow from the capacitor bank via the output to provide a variable power via the output. The flash generator further comprises a controller for controlling the switch, whereby by controlling the on time of the switch, the generator is operative to provide,during a time period of 100 to 2000 µs during a peak time period within the time period,an average power at least 4 times higher than the average power provided during the other time period within the time period, whereby the flash tube during the peak time period becomes fully ignited.
Abstract translation: 本公开涉及一种用于向闪光管提供电源的闪光发生器,使得闪光管快速提供适于FP同步平坦峰值的光输出。 闪光发生器包括电容器组,输出和开关,其被配置为经由输出从电容器组切换电流,以经由输出提供可变功率。 闪光发生器还包括用于控制开关的控制器,由此通过控制开关的接通时间,发生器可操作以在时间段内的峰值时间段期间在100至2000μs的时间段期间提供平均值 功率比在该时间段内的其他时间段内提供的平均功率高至少4倍,由此闪光管在高峰期间变得完全点燃。
