Design of inverter and grid connected phase locked loop based on DSP control for photovoltaic power generation |
| |
| Abstract: | This paper designed solar photovoltaic inverter power grid phase locked loop system based on the DSP software control. The phase locked loop tracking control is realized by using the pointer to ze-ro method, and the design of the phase locked loop is applied to the PV grid connected inverter. The sim-ulation model was built in MATLAB. The simulation results show that the phase locked loop of this paper can meet the requirements of the synchronization performance of PV inverter system, it is of high popular-ization value. |
