| Abstract |
This paper focuses on the harmonic at the
network of the driving systems with DC motors and
controlled rectifier. Notably, the total harmonic distortion
factor (THD) is influenced by the rectifier commutation and
by the load current filtering. We found these influences
(thyristors commutation and filtering inductivity)
concerning the waves of the currents in the secondary of the
transformer and in the network and the waves of the voltage
in the secondary of the transformer, as well as the
correspondent harmonics spectra. The achieved MATLABSIMULINK
model corresponds to a driving system supplied
from a three-phase controlled rectifier. The numerical
results are accompanied by experimental verifications,
which validate the Simulink models and we done a
comparison by IEC 1000-2-1 relation. The active harmonics
filtering in dynamic state is discussed. |
