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 2 N , 3 N , 4 N and 6 N 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.
