Abstract

This paper presents a new 36-pulse star connected rectifier. It takes intimate sinusoidal currents from utility with the elimination of lower than 35th order harmonics. The proposed rectifier consists of a parallel four-star 12-pulse diode rectifier and two passive injection circuits at DC links. This passive injection circuit can triple the number of pulses of 12-pulse star rectifier system. The primary side of specially tapped interphase transformer (STIT) with two diodes constitutes the first injection circuit while the secondary winding of the STIT with a single phase full-wave rectifier (SPFR) constitutes the second passive injection circuit. This rectifier is compatible for large current rating application such as electroplating, plasma torches, dc arc furnaces etc. The simplicity of the proposed rectifier scheme makes it more economical compared to other existing designs of same performance. The proposed rectifier is examined and simulated in MATLAB environment. The simulation result confirms the requirement of IEEE-519 standards.

一种新型直流链路无源注入36脉冲星形整流器

本文介绍了一种新型36脉冲星形连接整流器。它在消除了低于35次谐波的情况下，从公用事业中获得了亲密的正弦电流。所提出的整流器由并联四星12脉冲二极管整流器和直流链路上的两个无源注入电路组成。该无源注入电路可使12脉冲星型整流系统的脉冲数增加三倍。带有两个二极管的特殊抽头间相变压器(STIT)的一次侧构成第一注入电路，带有单相全波整流器(SPFR)的STIT的二次绕组构成第二无源注入电路。该整流器适用于大电流应用，如电镀、等离子炬、直流电弧炉等。所提出的整流器方案的简单性使其与现有的相同性能的设计相比更加经济。在MATLAB环境下对所设计的整流器进行了测试和仿真。仿真结果证实了IEEE-519标准的要求。
