Abstract:This paper proposes an optimized topology of hybrid active third-harmonic injection matrix converter (H3IMC), which mitigates input current distortions at sector boundaries. First, the research background and working principles of H3IMC are introduced. Then, the origin of the distortions is analyzed from the angle of commutation. To solve this problem, a modification of the original topology is proposed, which has a dc-link filter to bypass the switching frequency component of IVS output currents and then reduce the mutation in input currents. Moreover, the concept is verified by simulation results taken on a H3IMC Simulink model. Finally, the mains current quality and the number of passive elements used in the original optimized topology and are compared. © 2018 KIEE EMECS (KIEE Electrical Machinery and Energy Conversion Systems).
