| Abstract: | According to the characteristic of photovoltaic grid-connected inverter system,the paper adopts the mode of the hys- teresis-band current control to study 3kW single phase photovoltaic grid-connected inverter Theoretical analysis to the hys- teresis-band current control method, and simulated module is constructed by using Matlab/Simulink to make simulation ex- periment.Simulation results show that,the control method to ensured the quality of the inverter output current waveform,make the system output current and grid voltage have the same frequency and direction,and the power factor after interconnec- tion close to 1.Meanwhile,the total harmonic distortion （THD） is analyzed. |
