Abstract :
Normalized design relationships are presented for line-current harmonics, line-current fundamental phase angle, displacement power factor, purity factor, overall power factor, and DC output voltage as a function of firing angle and noninfinite output filter inductances for both single- and three-phase phase-controlled rectifiers. The design relationships are useful for both the analysis of existing rectifiers and the design of new rectifiers. These accurate design relationships are essential for attacking the problems caused by high rectifier line-current harmonics and low power factor.<>
