基于双抽头电抗器的48脉波整流系统分析及MATLAB仿真
Analysis and MATLAB simulation of 48-pulse rectification system based on two-tapped inter-phase reactor
摘要
Abstract
Multi-pulse rectifier has been widely used in electrolytic aluminum and DC traction power supply system of metro due to high output power quality and low harmonic distortion of the input AC line current.A mathematical method based on 24-pulse rectifier system with stretch triangle connection at the primary side of the transformer is used to accomplish 48-pulse rectifier system.The tap ratio to realize 48-pulse rectification is obtained through this mathematical method.The input AC line current and circulating current are analyzed by MATLAB/Simulation.The simulation results show that the ideal 48-pulse rectification can be achieved by two-tapped inter-phase reactor,meanwhile,the input AC line current harmonic is suppressed and the THD is reduced.关键词
