This paper proposes the voltage/current double-loop control PWM method to depress the harmonic. After that, the PID controller's parameter design method is researched to depress the harmonic better. At last, the output current of the inverter is analyzed through the GCPV model accomplished in MATLAB considering the change of the light intensity. The result is good(the harmonic content is within the scope of the standard) and the dynamic performance of the GCPV is well when adjusting the PID controller's parameters. The simulation results prove the effectiveness and value of this paper's harmonic depression method.
