摘要
数字信号处理器(DSP)芯片控制的在线式不间断电源(UPS)。基于DSP芯片的使用大大提高了整机的集成度,同时数字控制还带来可编程、抗干扰强、可靠性高、效率高等优点。本文介绍了提高输入功率因数的数字在线不间断电源,通过实时控制输入电流的波形,总的谐波分量大大减少。
An on-line UPS controlled by one DSP controller.The application of DSP greatly increases integration and digital control brings the advantages of programmability,immunity to noise,improved reliability and high efficiency etc. This article introduced the method of enhancing the power input factor in the digital online UPS, by controlling the input current profile, the power factor approximates 1, the total harmonic component reduces greatly.
