基于DSP的不间断电源控制技术研究

Research on Uninterruptible Power Supply Control Technology Based on DSP

传统化的正弦波脉宽调制控制(SPWM)技术与相控技术均在不间断电源电路控制方面存在诸多局限,随着信息化改革的深入,数字信号处理器(DSP)成为控制不间断电源(UPS)的主流趋势。基于此,本文首先阐述了不间断电源的工作原理,提出DSP不间断电源控制技术的运行流程,分析DSP控制不间断电源的关键电路结构,进一步围绕控制实例展开探讨,以供参考。

The traditional sine wave pulse width modulation control(SPWM)technology and phase control technology have many limitations in the control of uninterruptible power supply circuits.With the deepening of information reform,the digital signal processor(DSP)has become an uninterrupted control Main trend of power supply(UPS).Based on this,this article first expounds the working principle of uninterruptible power supply,proposes the operation flow of DSP uninterruptible power supply control technology,analyzes the key circuit structure of DSP control uninterruptible power supply,and further discusses the control examples for reference.
