Abstract

The recent development in the power electronic devices leading to increasing use of power electronics converter in industrial and domestic applications. These power converters provide many advantages and flexibility in these applications, but at same time causes harmonic distortion in the power system. In various industrial applications, the DC choke are preferred harmonic mitigation solution due to less cost and smaller size. However, in many industrial plant small AC choke are used to improve the performance of power converter against grid disturbances like transients. Therefore, due to presence of AC choke, it is possible to optimize the size of DC choke in power converter, which can further reduce the cost and size of converter but still fulfill the harmonic requirements. In this paper, a mathematical model is developed to describe the relation between AC choke and DC choke inductances. The proposed model is analyzed by number of simulation studies and then verified by experimental results.
