Design and Rating Comparisons of PWM Voltage Source Rectifiers and Active Power Filters for AC Drives With Unity Power Factor Academic Article uri icon

abstract

  • Given terminal constraints of unity power factor in ac drive applications, two ac drives are possible: one with a pulse-width modulation voltage source rectifier (PWM-VSR) and the other using a diode rectifier and an active power filter. Despite numerous publications for the two drives, the features and advantages between them have not been clearly explained. This paper presents a theoretical analysis and systematic comparison between the two drive topologies. Converter kVA ratings, dc-link voltage requirements, switch ratings, semiconductor losses, and reactive component designs are considered for the evaluations. © 2005 IEEE.
