Abstract	This study describes the methodology and the basic procedure developed by the patent entitled New Configurations of DC -DC Converters of One Input and Multiple Outputs without Transformer and Power Converter that Apply Them. The invention is related with new configurations of DC -DC converters of single input and multiple outputs (SIMO), without a transformer, with a single power switch, and therefore a single control circuit, which results in a smaller size, lower weight and simplicity compared to other known SIMO DC–DC configurations. In a novel form, it comprises at least two converters which share the DC source, an inductor and the power switch. This is obtained by the combination of basic converters: step-down (buck), step-up (boost) and step-down/step-up (buck–boost) as ?uk converter, SEPIC (single ended primary inductance converter), Zeta, CSC (canonical switching cell) and buck -boost single-inductor. A generalisation of the methodology developed in this invention allows to obtain modular converters with 2N, 3N, 4N and 6N outputs and single input, from N converter modules. The paper also relates to a power converter, comprising N (greater than or equal to 2) DC converters connected in parallel, whose control signals have a phase shifting of 2π/N radians.
