Modeling and Control Design of the Six-Phase Interleaved Double Dual Boost Converter

This paper presents the small-signal modeling and the control design of the six-phase Interleaved Double Dual Boost, which is a non-insulated, step-up DC-DC converter that can be operated with high voltage gain and can be scaled to high-power applications. The applications of this converter include electrical vehicles and renewable energy conversion. Experimental results obtained with a prototype operating with input voltage of 60V and output voltage of 360V and with nominal output power of 2.2kW are presented.
