文章介紹了一種以直接數(shù)字頻率合成（DDS）技術(shù)為基礎的波形發(fā)生器，設計了硬件電路，并給出了主要的電路原理圖，給出了軟件流程圖和部分核心軟件代碼。該波形發(fā)生器應用在加速器磁鐵電源控制系統(tǒng)中，用來產(chǎn)生控制電源所需要的波形信號，本文中的設計對于需要用波形信號來控制設備的系統(tǒng)具有普遍的實用價值。

Abstract: A kind of waveform generator based on direct digital frequency synthesizer
is introduced in this paper, the hardware circuit and the main principle chart are
presented, the software flow chart and some of the core software code is presented too.
This kind of waveform generator can be applied on accelerator magnet power control
system to generate the waveform signal to control power, the design of this paper have
prevalent utility value for those need waveform signal to control facility.
Keywords：DDS, AD9832, waveform generator, power control.
