The generator includes multiple power converter (MPPC) and HT rectifiers (HT tank), which together produce a positive polarity high voltage (HT) and fi- lament power supply current. Working principle and maintenance are described of PANalytical (formerly Philips) PW2440 fluorescence spectrometer high voltage generator.
