Circuit Analysis and Maintenance of High-Voltage Generator of PANalytical XRF Spectrometer

X射线管高压发生器是荧光光谱仪的核心部件之一，它提供一个的的高压供电电源给Ｘ射线管，是获得分析的必要条件。它包括多路电源变换器(MPPC)和HT整流器(HT油箱)，二者共同产生一个正极性的高压(HT)和灯丝供电电流。本文介绍了帕纳科(原荷兰飞利浦) PW2440荧光光谱仪高压发生器的工作原理及其故障维修。

The X-ray tube high voltage generator is one of the core components of fluorescence spectrometer which provides high-accuracy high-voltage power supply to the X-ray tube and it is necessary to obtain high-precision analysis results. The generator includes multiple power converter (MPPC) and HT rectifiers (HT tank), which together produce a positive polarity high voltage (HT) and filament power supply current. Working principle and maintenance are described of PANalytical (formerly Philips) PW2440 fluorescence spectrometer high voltage generator.
