Abstract This paper analyses the LCL-type grid-connected filter firstly. It gives proper designing steps. Through Matlab simulation, we get the affection of the ratio of the grid side inductor and the converter side inductor to the filter capacitor value and the cripple current. Simultaneously it analyses the application of the active damping control strategy into the LCL-type grid-connected filter. Then it analyses the splitting capacitor-type high order filter in detail. We get the affection of the splitting capacitor values to the filter performances, and the experimental waveforms using this type high-order filter into the static var generator. Finally basing on the splitting capacitor-type high order filter, it adds a LC trap branch, and analyses the affection of the damping resistor to the filter performances. We also get the experimental waveform using this type high-order filter into the static var generator.
