Design considerations for 12/24-pulse auto-connected rectifiers for large VA, PWM drive systems Conference Paper uri icon

abstract

  • Auto-connected multipulse (12/24 pulse) rectifier schemes are cost-effective methods for reducing line current harmonics in PWM motor drive systems. Employing these schemes to enhance utility power quality requires careful attention to several design considerations. In particular: excursion of DC-link voltage at no load; effect of pre-existing voltage distortion; impedance mismatches; unequal diode drops on rectifier current sharing; and performance are fully analyzed. Several corrective measures to improve the performance of 12/24-pulse rectifier systems are also discussed. Finally, experimental results on a 460 V, 60 Hz, 400 kVA commercial ASD, retrofitted with 12/24 pulse rectifier systems, are discussed in detail
