Abstract :
The principle of photovoltaic grid-connected generation system is analyzed, and the research on PWM control strategy is done based on the power output side of photovoltaic grid-connected generation system. The direct current control strategy of photovoltaic grid-connected inverter is presented. The control fashion of applying fixed switch frequency and the feedforward compensation control of utility grid voltage is introduced. The current response speed is proved to be faster, and the grid-connected current waveform is sine and the power factor is unity
