摘要：

This paper presents a comparative analysis of three dc-dc non-isolated buck converters. For this purpose, a classical buck converter, an interleaved buck converter, and a three-state switching cell (3SSC) buck converter were analyzed. In order to best compare the performance of these topologies, the switching frequency, processed power, current ripple before the filter capacitor, and specification were considered equals for all tested configurations. A modular prototype of 1 kW, 200 Vdc / 60 Vdc was implemented, allowing to easily configure all topologies by just changing the magnetic components. From the experimental results, it was found that all studied converters present some current unbalance, being the less critical in the converter based on 3SSC.
