Extended methodology to synthesize high step-up integrated DC-DC converters

This paper proposes an extended methodology to generate high step-up DC/DC converters. The methodology is based on integration of the common circuits of the standard non-isolated DC/DC converters and association of the converters output sections. For the integration of two non-isolated converters, the output sections are series connected, meanwhile parallel and cascaded connection are only possible for the integration of one isolated converter with a non-isolated one. Further simulation and experimental analyses are carried out for the Integrated boost-Zeta and Integrated boost-flyback converters.
