Modeling and Control Design of the Interleaved Double Dual Boost Converter

The Interleaved Double Dual Boost is a noninsulated, step-up DC-DC converter capable of high voltage gain and suitable to high-power applications. In this paper, the modeling and control design of this converter, valid for an arbitrary number of phases, is presented. The developed approach is then applied to a six-phase Interleaved Double Dual Boost and experimental results are obtained with a prototype operating with input voltage of 60V, output voltage of 360V and with nominal output power of 2.2kW. The applications of this converter include electrical vehicles and renewable energy conversion.
