摘要
针对通用变频器能量传输的不可逆性,以及传统能量回馈系统回馈的电流谐波含量较大的缺陷,设计了一种基于DSP控制器——TMS320F2812为核心器件,采用电流跟踪技术和正弦波细分技术来实现能量回馈控制系统。实验结果表明:由该方法得到的回馈电流波形中所含的谐波成分较低,并且回馈电流波形具有良好的正弦性。
Based on the general converter for energy transmission is not reversible, as well as the feedback current of the traditional energy feedback control system contains high harmonic,a novel energy feedback control system was designed with the controller of digital signal processor-TMS320F2812 as the core device. In order to achieve the energy feedback control system, the technology of current tracing and sinewave microdivision was utilized. The experimental results show that the feedback current based on the above method contains lower harmonic and has better sinusoidal nature.
