“…Multipulse rectifier (MPR) is one of the most common rectifiers in high power rectification system due to its simple configuration and high reliability, such as high-voltage dc transmission, aircraft converter system, telecommunication power supplies, electrochemical processes, ship propulsion system and plasma power supplies [1][2][3]. In order to improve the power quality in MPR and comply with the power quality standards, a lot of research have been done on total harmonic distortion (THD), power factor (PF), voltage distortion and so on [4][5][6][7][8][9][10][11][12][13][14][15][16]. Increasing the step number of input line current to draw sinusoidal input current is the common and effective way to reduce the THD.…”

This study presents a comparative analysis of two different interphase reactors (IPRs) applied in a 36-pulse diode rectifier. One is traditional triple-tapped IPR; the other is unconventional IPR (UIPR) composed of the primary winding and secondary winding. The primary winding is double-tapped conventionally and the secondary winding is connected with a singlephase full-wave rectifier. The operation modes and optimal parameters of both IPRs are analysed. The effect of different operation modes on output currents of the two three-phase diode-bridge rectifiers, input currents and load voltages is also analysed. Under the optimal parameters, both rectifiers operate as 36-pulse diode rectifiers and reduce the total harmonic distortion of input line currents to be 5%. Especially, the proposed rectifier using UIPR is easy and simple to implement. Some experiments are provided to validate the theoretical analysis.

“…In Kalpana et al, 12 a DC side current injection has been utilized to reduce the harmonics. In Meng et al and Yang et al, 14,15 12-pulse rectifiers using passive auxiliary circuit at dc link are proposed. A Vienna rectifier has been reported in Izadinia and Karshenas, 13 which can enhance the power quality of the multi-pulse rectifier.…”

“…The proposed system of this paper has a simple design and control-free structure, reducing the complexity of the system. In Meng et al and Yang et al, 14,15 12-pulse rectifiers using passive auxiliary circuit at dc link are proposed. In these methods, the interphase reactor (IPR) has been replaced using a multi-tapped IPR.…”

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.

“…A imposição triangular aumenta a corrente média do autotransformador [4], [10], mantendo o mesmo nível de potência exigido pela carga. Essa imposição, embora benéĄca para a qualidade das correntes de entrada reduzindo signiĄcatimente o THD em estruturas de múltiplos pulsos [12], e do fator de potência, gera um aumento na potência processada do núcleo magnético do autotransformador, que inicialmente era de 18,34% a 20,5%, gerando uma diminuição na potência de saída na qual o autotransformador foi originalmente projetado.…”
