A single- phase current source type converter generates many harmonic components in the input current. These harmonics may cause various disturbances in the power distribution systems.
In this paper, we propose a reduction method of the harmonic currents based on the principle of constant resistance circuit. The configuration of proposed circuit is simple owing to use of passive elements only. The principle of harmonic currents reduction in this method and the design method of the circuit constants are described. We carry out the analysis of this circuit, and clarify the reduction effects of harmonic currents and the quantity of the power loss.
From these results, it is clarified that this method is very effective and useful.
