摘　　要：针对传统能量回馈系统中回馈电流谐波含量较大这一缺陷,本文提出了一种以数字信号处理器(DSP)为核心器件,采用正弦波细分方法来实现的能量回馈控制方案。首先给出了控制系统的设计思路,然后给出了软件设计方法,最后进行了实验研究。实验结果表明:该方法得到的回馈电流中所含谐波成份较低,并且回馈电流波形具有较好的正弦性。Considering the fact that feedback current of general energy-feedback control system contains high harmonic,a novel control system with technology of the sine-wave microdivision is designed. Firstly, the paper states the design of control circuit,then introduces the design method of software for the system, at last an experiment is carried out. The feedback current based on the above method contains lower harmonic and has better sinusoidal nature through the experimental results.
