Multiport converters have tremendous performance over conventional solutions that employ multiple single converters in multi‐input and multi‐output applications. Furthermore, they provide the most economic operation and improve the performance of the system. Hence, in the recent past, a lot of development and research have been carried out for developing the single‐input–multi‐output (SIMO) converters in various aspects which are presented in the study. These topologies have some assumptions which are made on the charging of inductor current and design of duty cycle for achieving multiple outputs. In this study, an SIMO DC–DC converter is proposed. It independently regulates both the outputs at different voltage levels and none of the assumptions are made on the basis of inductor charging currents ( i L1 > i L2 or i L1 < i L2 ). Cross‐regulation problems do not exist, so the output voltage V 01 ( V 02 ) is not influenced by the variation of load current i 02 ( i 01 ), also the proposed converter has the ability to avoid the common grounding problems between the outputs. Low‐power (200 W) prototype circuit is developed to verify the feasibility of the proposed converter and the experimental results are validated with simulation results.
