Measurement result from 1 to 48 fluorescent lamps in the frequency range 2 to 150 kHz

摘要

This paper present measurements performed in the lab where experimental setup of 48 fluorescent lamps powered by high-frequency ballasts. The frequency range of interest is above the traditional harmonic range from 2 kHz up to 150 kHz. In this frequency range the measurements distinguish between two distortions found; recurrent oscillations and remains from the switching at the active power factor correction circuit.
