The method of PI regulator fusion integral feedback is used to not only improve the inverter output characteristics, but also achieve the capacitance characteristics of inverter.Because the capacitive inverter has similar characteristics with reactive power compensator in micro grid,capacitive depth of the inverter is designed to be adjustment,which can adjust the control parameters for reactive power compensation to meet actual requirement.A simpler,more visualized,and more efficient verification method is proposed to improve the current verification method for capacitor property of inverter....
