摘要
介绍了并网逆变系统的结构和原理,设计了一套基于SPWM的双闭环并网逆变方案。利用数字信号控制器dsPIC30F4011设计了一台原理样机,实验结果表明系统母线电压稳定,并网电流正弦性好,功率因数接近-1,并且具有良好的动态特性。
Structure and principle of the grid-inverter system is described, and a program is designed based on double-loop SPWM. A prototype is designed using digital signal controller dsPIC30F4011 and the experimental results show stability of the dc bus voltage and smooth sine of the grid-connected current. System can get a nearly -1 power factor, with an outstanding dynamic characteristic.
