“…Up to 40-pulse AC-DC converters have been addressed in Paice and Singh et al 4,5 presenting different applications of multi-pulse technique, but the proposed schemes lead to violation of IEEE 519 6 and MIL STD 1399 requirements (ie, 3% for the input current total harmonic distortion [THD]). Various configurations have been reported for 12,18,20,24, and 30-pulse converters, [7][8][9][10][11] and the experimental results have been obtained to support presented ideas. Using active auxiliary circuit is also a typical harmonic reduction method at DC link.…”

“…It means that the required magnetic rating of the proposed topology is about 44.33% of the load rating while the current THD is less than 3%. 12 It should be noted that the transformer magnetic ratings determine the total cost and size of the system. For example, it can be seen that 57.26% 17 and 63.98% 18 of magnetic rating have been used to achieve THDi<5% in 40-pulse AC-DC converters.…”

“…The hysteresis and eddy current losses are given as follows: (12) where, K h is a proportionality constant that depends on the volume and quality of the core material used, K e is a proportionality constant that depends on the volume and resistivity of the core material used, B m is the maximum flux density, and f is the frequency of the alternating flux. Core losses consist of hysteresis losses (P h ) and eddy current losses (P e ).…”

In this paper, a new multi-pulse clean power converter topology is presented with lower than 3% input current total harmonic distortion (THD). The topology is based on the combination of a 36-pulse converter and a pulse doubling circuit. The 36-pulse converter consists of a "polygon" autotransformer and two 18-pulse diode bridge rectifiers. Pulse doubling circuit consists of zerosequence-blocking transformer (ZSBT) and tapped interphase transformer (IPT). The important advantage of the proposed AC-DC converter is considerable reduction in burdens of the magnetic parts with respect to the nominal load rating. It provides more economical solution to achieve harmonic mitigation in electric power systems as compared with other 72-pulse AC-DC converters. The simulation and experimental results show that the input current THD is less than 3% using the proposed topology. The results indicate a significant reduction in the total cost and volume of the proposed 72-pulse configuration in comparison with similar configurations. Also, it is shown that the proposed converter rating is about 44% of the DC load power.
