| Abstract: | According to the requirement of the application of photovoltaic system, the principle and control strategy of grid connected and off grid inverter modes are discussed. A nonlinear quasi proportional resonant(PR)controller for the inverter of PV system is proposed in this paper. The introduce of the nonlinear unit can increase the system at the beginning of the response, and to improve the swiftness of the system response. The effect of the nonlinear unit can eliminate the distortion at the switching moment, and to guarantee the smooth effect of inverter. Finally, the feasibility and effectiveness of the proposed method are verified by Matlab/Simulink simulation. |
