A case study: the performance of power conditioning unit in freescale semiconductor Sg.Way Petaling Jaya Selangor / Md Raziff Zainal Abidin

Freescale Semiconductor (FSL's) primary concern in respect of removal of the Power Conditioning Units (PCUs) is the risk of production loss through the exposure of the tester and handler to unacceptable levels of power quality, voltage sag, and harmonic. In recent years, with the increase number of testers drawing non-sinusoidal currents, power quality distortion has become a serious problem in FSL electrical power systems. In this paper, to access the impact voltage sag on the selected testers and their associated handler, evaluations of harmonic and the performance of the power conditioner have been studied. Then after theoretical study, harmonic and several power quality indices have been measured in a factory. The measurements show that based on the results of the tests conducted both the Piller and Datawave Power Conditioning Units (PCUs) offer good isolation of the input power supply from the harmonic loads and vice versa. Both also offer voltage sag correction and harmonic mitigation.
