“…This rating is less than many other topologies of AC-DC converters. 18 Although the kVA rating of the proposed configuration is slightly higher than 36 pulse, its THD is less than the 36-pulse converter. Table 3 presents the active magnetic rating and cost comparison of the proposed 72-pulse with the 36-pulse converter, 40-pulse converter of Singh and Gairola, 17 and 40-pulse converter of Abdollahi and Gharehpetian.…”

“…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.…”

“…But, the THD of the supply current is more than 3% when operating at light load. Another T-connected autotransformer-based 40-pulse AC-DC converter has been reported in Abdollahi and Gharehpetian, 18 which has THD variation of 2.55% to 3.79% from full load to light load, which is more than 3% when operates at light load.

“…A polygon-connected autotransformer-based 40-pulse AC-DC converter has been reported in Singh and Gairola, 17 which has THD variation of 2.22% to 3.85% from full load to light load (20% of full load), respectively. Another T-connected autotransformer-based 40-pulse AC-DC converter has been reported in Abdollahi and Gharehpetian, 18 which has THD variation of 2.55% to 3.79% from full load to light load, which is more than 3% when operates at light load. In some applications, it is necessary to take strict power quality measures.…”

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.

Abstract. Using the traditional phase-shift angle, the differential delta-connected transformer is not able to boost voltage. Broadening the phase-shift angle of the autotransformer can boost its output voltage. But the greater phase-shift angle will increase the equivalent kilovolt ampere (KVA) rating as well. This paper analyzes the effect of phase-shift angle on the input currents and the equivalent (KVA) rating of the differential delta-connected transformer. A novel phase-shift angle is proposed, with which the differential delta-connected transformer is suitable to be a step-up autotransformer, meanwhile, the equivalent KVA rating of the autotransformer is still smaller than the isolated transformer. Some simulation is carried out to verify the correctness of the analyses.

In this paper, a novel full-wave 12-pulse rectifier with simple circuit configuration is proposed. The proposed full-wave 12-pulse rectifier consists of a conventional six-pulse full-wave rectifier and an auxiliary single-phase full-bridge rectifier (ASFR). The ASFR extracts a rectangular current from the DC side of the rectifier to increase the output states of two three-phase half-wave rectifiers, then the conventional six-pulse full-wave rectifier is upgraded to a 12-pulse full-wave rectifier in accordance with the current relationship between AC and DC sides and the relationship between DC-side voltages. Since only a low-capacity ASFR (6.3% P d) is needed, the proposed 12-pulse rectifier has the least number of components count, making it robust and simple to implement. The average output current of ASFR is only 6.7% of the load current, which makes it more suitable for low-voltage and high-current applications. A prototype with a power of 1 kW is built to verify the correctness of the theoretical analysis.
