Abstract

A device for controlling active and reactive power based on a three-phase current converter (current inverter) with an output CL filter (grid controller) is considered. The consideration is focused on comparing filter characteristics and the effect of filter parameters on the current generated by the controller. Two filter circuits have been analyzed, which differ in the method of connecting a damping resistor. A method is proposed for determining the parameters of the output filter elements, in which the resistor is connected in parallel with the choking coil. The results of calculating the filter parameters have been verified by simulation using SimInTech software package.
