Abstract
  In recent years, to increase the number of pulses in 12-pulse autotransformer rectifiers (12-PARs) and reduce the input current total harmonic distortion (IC-THD), without increasing the cost and complexity, the technique of pulse multiplication circuit has been proposed. With this approach in this paper, ...  Read More

Abstract
  The 12-pulse diode rectifier (12-PDR) fails to comply with the limits of total harmonic distortion (THD) of supply current to be less than 5% specified in the IEEE Standard 519. Passive harmonic suppression circuits (PHSCs) have been observed to be a viable and cost-effective solution to improve the ...  Read More
