WebDec 1, 2004 · A 6-pulse rectifier will typically have about 30% THD, rich in 5 th and 7 th harmonics. A 12-pulse rectifier will have less than one-half of the THD that we see in a 6-pulse rectifier and is rich in 11 th and 13 th harmonics. UPS manufacturers can provide passive filter to reduce the total harmonic distortion that the generator sees.
