the principle of harmonic generation in a PWM adjustable speed drive (ASD) system and the influence of the long cable outlet have been analyzed A novel topology is presented including 24-pulse rectifier
three-level inverter
etc. In the topology
neutral points of the rectifier
the DC-link
the output filter
and the neutral clamped point of the three-level inverter are got together and merged into the ASD’s grounding via a low resistance. Based on the simulation results
an important conclusion can be drawn that the presented topology is effective to eliminate harmonic.
