Abstract

Paralleling power converters can increase the power rating and reliability of the overall system. Interleaving the carrier in parallel converters helps in reduction of output current distortion, and in reduction of electromagnetic interference noise. This study presents a common-mode inductor design for parallel interleaved converters, which integrates the inter-phase and boost inductors together in a novel structure. It is shown that the proposed magnetic structure accommodates a wider range of desirable electromagnetic parameters. Step-by-step design procedure of the proposed integrated common-mode inductor (ICMI) is presented. The proposed ICMI design results in fewer components, reduces the size and the cost of overall system. The proposed ICMI is compared with a design available in literature using an example. Existing design procedure imposes constraints on the core geometry that are not suitable for high-power designs. The proposed design makes use of standard C cores that improves manufacturability. Experimental results from a 7.5 kVA parallel single-phase power converter show the effectiveness of the proposed ICMI.
