- This article examines a system composed of two recently proposed dc-dc converter topologies, the double dual buck and boost converters, which are variations of the interleaved converters. In this setup, the individual converters operate in synchronous mode and are connected in cascade. Its operation involves the double dual boost increasing a low voltage, unregulated dc source, while the double dual buck acts as an inverter with a 120V ac output. The benefits of this system are a large voltage gain and power balance between stages, which lead to good performance and power quality, which makes it feasible for renewable energy system applications. Prototypes were built to validate experimentally the advantages of the proposed system. © IET Conference Proceedings. All right reserved.
