首发时间:2021-05-10
摘要:随着电力电子技术的发展,工频整流器作为电网与工业设备的接口应用广泛,但是由于电力电子器件的非线性,导致整流器会向电网中引入大量的谐波,常规的基于有源和无源谐波抑制的多脉波整流技术虽然能抑制谐波,但各自却存在不可忽视的缺点,因此本文将结合有源与无源谐波抑制技术,提出一种新型的混合型平衡电抗器,分析了该混合型谐波抑制的原理,根据其谐波抑制原理分析出其有源无源混合配比的最佳方案,给出了混合型平衡电抗器的软硬件设计,本文通过仿真和实验验证了混合型平衡电抗器提高了谐波抑制能力,降低了输出电压纹波。

Hybrid Inter-Phase Reactor based on Single-Phase Bridge Rectifier Technology
Abstract:With the development of power electronics technology, power frequency rectifiers are widely used as the interface between the power grid and industrial equipment. However, due to the nonlinearity of power electronic devices, the rectifier will introduce a large number of harmonics into the power grid. The conventional ones are based on active and passive Although the multi-pulse rectification technology of harmonic suppression can suppress harmonics, each has disadvantages that cannot be ignored. Therefore, this article will combine active and passive harmonic suppression technologies to propose a new type of hybrid balanced reactor. The principle of the hybrid harmonic suppression is analyzed, and the optimal scheme of the active and passive mMulti-pulse Rectification based on Hybrid Harmonic Suppression Technologyixing ratio is analyzed according to the principle of harmonic suppression. The software and hardware design of the hybrid balanced reactor is given. This article is verified by simulation and experiment. The hybrid balanced reactor improves the harmonic suppression capability and reduces the output voltage ripple.
