| Abstract: | 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. |
