摘要
在此设计了基于数字信号处理器(DSP)的光伏并网逆变器并网控制系统,通过检测逆变器输出侧和网侧电压、电流相位差,并通过DSP程序实现空间矢量脉宽调制(SVPWM)算法作为功率因数校正器来控制并网。搭建了基于TMS320F28335型DSP为控制器的实验平台,实验结果验证了所设计方法的有效性。
A novel grid-connected control system based on digital signal processor（DSP） of three-level inverter is proposed.The phase difference of the inverter＇s output side and the grid＇s is measured simultaneously by the DSP.The modulation algorithm of space vector pulse width modulation （SVPWM） is regarded as power factor corrector.The experimental platform is set up based on one chip DSP TMS320F28335 as the controller.The validity and superiority of the strategy are verified by experimental results.
