摘要
研究了基于两抽头平衡电抗器和基于辅助单相全波整流器的两种24脉波整流器直流侧谐波抑制机理。根据两抽头平衡电抗器和单相全波整流器的结构及安匝平衡原理,分析二者的功能及工作模式,研究了不同工作模式对整流器输入电流的影响,并给出两种整流器变比的理论最优值。理论分析及实验结果表明,两种24脉波整流器中二极管工作模式不同,在各自最优条件下,都能消除输入侧电流的12k±l(k为奇数)次谐波。
The harmonic reduction mechanism at DC link of two kinds of 24-pulse rectifiers with double-tapped interphase reactor and auxiliary single full wave rectifier is researched. According to the structure and ampere-turn balance with double-tapped interphase reactor and single full wave rectifier, the function and operation mode of two kinds of rectifiers are analyzed.The effect of different operation mode on input current of rectifiers is also analyzed and the theoretical values of turn ratios of two kinds of rectifiers are calculated .Theoretical analysis and experimental results show that the operation modes of diodes connecting to interphase reactorare different in both 24-pulse rectifier. In addition , under the optimal condition , both 24-pulse rectifiers can reduce the ( 12k±1)^th(k is odd number) harmonics.
