要約(英語): Buck-boost converters with a large current capacity are required for batteries in renewable energy systems. Although interleaved converters are a typical solution to enhance the current capacity, additional components and feedback control loops are required to balance phase currents, resulting in increased circuit complexity and cost. Furthermore, the inductor current ripples of buck-boost converters tend to be larger than those of buck or boost converters. This paper proposes the interleaved buck-boost converter with passive current balancing and inductor current ripple reduction. Flying capacitors are incorporated to not only to balance the capacitive current but also reduce inductor voltage and current ripple. An experimental verification using a 300W prototype demonstrated that the passive current balancing capability and inductor current ripple can be reduced.
