摘要
近正弦输入电流三相整流器(Rectifier with Near-Sinusoidal Input Current,简称RNSIC)结构简单,可以很好地降低交流侧的谐波含量,是减小整流器谐波污染的有效途径,但它也存在着体积大、输出电压不稳定等缺点。分析了该整流器的缺点及其产生的原因,并提出一种针对性改进方案。实验表明,改进型整流器在体积和输出电压稳定性方面均比原整流器有所改善,同时具有原整流器输入谐波含量低,额定工作点功率因数高的优点。
Three-phase rectifier with Near-Sinusoidal Input Current（RNSIC） is used to effectively reduce harmonic with simple structure.The shortcomings such as the big inductor and the unstable output voltage are analyzed and an improved method to resolve them is put forward in this paper.Simulative and experimental researchs indicate that the improved rectifier not only has the advantages such as low-harmonic and high power factor which the original has,but also it is smaller and the output voltage is steadier than the former.
