| Abstract: | A dual-loop SPWM control method is used in single-phase voltage inverter by analyzing its topology and principle, and a limited-frequency hysteresis current control method is introduced to the grid-connected system to solve the problem that the frequency varies too fast that the traditional hysteresis current control method causes. A prototype is designed using digital Signal controller dsPIC30F2010 and the experimental results show the grid-connected system has both excellent steady-state behavior and dynamic performance. |
