三相电压型整流器DSP 控制的实现及程序模块化应用

摘要

Three Phase Voltage Source Rectifier ( VSR ) is one of most common used topologies of converter because of its high power factor, low harmonic distortion, simple construction and wide output power level covering from few thousand to megawatt.This paper is based on DSP program,developing its technology of rectifier,analyzing the construction of DSP program,and finding a way to modulating the pro-gram,which enhances its readability and decreases its length of code,reducing the cost of maintaining code. At last,the feasibility of DSP program is verified by simulating.%三相电压型整流器是当今非常热门的变换器拓扑之一，它功率因数高，谐波畸变小，拓扑结构简单，输出功率可以从几千瓦到兆瓦级。文章以程序算法为核心，实现了对整流器的DSP控制，分析了其应用程序的框架结构，并在此基础上提出了控制程序的模块化方法，增强了程序可读性，减少了代码长度，降低了维护成本。同时利用PLECS仿真软件对DSP程序进行了仿真，验证了其正确性。
