Abstract

The authors investigate the harmonic contents of the stator current, rotor current, and rotor voltage of a repulsion motor controlled by a triac in the rotor circuit. The waveforms of these variables were generated and then analyzed numerically for their harmonic content using a Fourier series subroutine. The results were validated by comparison with experimental results. The analyses show that less stator current harmonics are injected into the power system using a triac in the rotor. Since chopping takes place in the rotor, the induced harmonics in the stator are reduced in magnitude
