Abstract |
Elimination of 5th-and-7th line current harmonic components in 3-phase AC-DC converters may be achieved by current injection. Injected current 5th-and-7th harmonics must have the same order, the same rms values and the same phase-angles, respectively, as these of the harmonic components to be eliminated. Analysis of the rms values and phase-angles of 5th-and-7th line current harmonics of a 6-pulse AC-DC converter shows that rms values and phase-angles of the injected currents can be deduced from those of the fundamental component I1 of the line current. The injected currents are generated by a transistor converter which switches a direct current proportional to I1. |
