Power system harmonic analysis of a pulse DC sintering system

Pulse DC Sintering System (PDCS) produces metallic and nonmetallic samples in a cheap and efficient way in a short time. Some PDCS systems possess thyristor-based rectifiers to control their output power. This results in PDCS systems creating power system harmonics. The harmonic content of an PDCS system varies during sample manufacturing process since the PDCS container resistance is temperature dependent. In this study, power system harmonics of a PDCS system is examined for the first time in literature. A power analyzer device is used to measure and record the supply side current, voltage and power of the PDCS system as a function of time. Besides, an infrared temperature meter module is a used to measure PDCS container temperature and record it with respect to time during sample production. Total harmonic distortion is found to be decreasing with container temperature increasing.
