基于三相并网电流源型逆变器的新型无源阻尼拓扑分析

ype three-phase grid current source inverter traditional passive damping of the grid side inductance parallel resistance method, increase the system damping resonance to suppress the output filter, but its damping loss and high frequency harmonic attenuation rate is high, this paper based on the traditional scheme put forword two kinds of new type of passive damping topology. Mainly analyzes the structure of a new type of passive damping of the system parameter design method and under the same system parameters, the passive damping for two kinds of new type damping effect, ability of harmonic filter and damping loss are analyzed in comparison. Finally, in order to verify the proposed new topological properties and put forward a current source inverter output filter parameter design method is effective, respectively, through the Matlab/Simulink interconnection and interconnection test, verify the feasibility of the proposed topology and parameters design method is effective.
