摘要
在我国社会主义经济不断高速发展的情况下,各行各业都在不断的发展变革,其中电子设备也在不断的更新换代。矢量变频器是一种将直流电机变换成高频脉宽调制波形的电力电子元件,其输出电压谐波会影响交流电机,出现电能质量下降,功率因数降低的问题。本文针对传统矢量控制技术存在的问题及缺陷,提出了基于APF方法进行有效抑制策略研究。
Abstract
In the case of the rapid development of Chinas socialist economy, all walks of life are constantly developing and changing, among which the electronic equipment is also constantly upgrading. Vector inverter is a kind of power electronic element that transforms the DC motor into a high-frequency pulse width modulation waveform. Its output voltage harmonic will affect the AC motor, resulting in the problem of power quality decline and power factor reduction. Based to the problems and defects of traditional vector control technology, the effective inhibition strategy based on APF.
