摘要
为降低整流器成本,减少供电电网谐波,拟将一种新型三相、多脉波整流器应用到城市轨道交通供电系统中。该电路拓扑结构简单,采用一种低功率谐波注入电路以增强电路性能,并使电路具有24脉波特性;可实现网侧电流正弦化,谐波含量减少,整个谐波畸变率小于3%。通过仿真验证了该应用的可行性。
In order to reduce the cost of rectifier and the harmonic of power supply current, a three phases, multi-pulse rectifier circuit is applied in the power supply circuit of urban mass transit. The circuit topology is simple, which adopts a low power harmonic injection eireuit to enhance the performance of the circuit, and makes the circuit to have the 24-pulse characteristics Thus, the sinusoidal current in AC side is realized, the harmonic content is reduced to leas than 3% of the total harmonic distortion. The feasibility of the rectifier is proved with SIMULINK.
