摘要
针对现有的12脉波及多重化整流系统存在效率低下、整流变压器噪声大等问题,提出了一种基于感应滤波技术的新型整流变压器,并介绍了基于此变压器的常用不可控与可控工业直流供电方案,从谐波抑制、铁心谐波磁通抑制、功率因数提升、部件损耗降低及系统节能等几个方面进行了仿真对比分析。结果表明,新型工业整流机组具有谐波抑制效果优、节能等优点,其中可控直流供电方案在系统结构与节能方面优势更为明显。
In order to solve the problems of conventional 12-pulse and multiple rectifier system such as lower efficiency and larger noise of transformer, it presented a novel rectifier transformer based on inductive filtering technology, introduced normal uncontrollable and controllable DC power supply schemes with such transformers and comparatively analyzed harmonic suppression, harmonic magnetic flux suppression, power factor＇s promotion, loss decreasing and energy-saving of the system in Matlab simulations. Simulation results show that the new industry DC power supply units have the advantages of good harmonic suppression and energy- saving, and the advantages of the controllable DC power supply scheme are more distinct in terms of structure and energy- saving.
