A novel single input-multi output DC/DC converter has been developed to feed the loads that have different voltage levels. For independent voltage control and high voltage gain, the converter has two layers as positive and negative. The presented design of converter structure has been analyzed theoretically and its state equations have been worked out. Theoretical analysis has been tested in MATLAB environment and verified with successful results. During simulation studies, voltage control of power layers was realized by adjusting the duty cycles of the switches with a PI controller. It has been observed from the simulations that the model presented operates successfully under the variable input voltage and different output voltage conditions and the output voltages are controlled as independent from each other. Once the model has been verified in simulation environment, a real prototype has been designed and then voltage control and efficiency tests have been performed experimentally on the prototype. Results show that the operating efficiency of the system is between 75-88% and the output voltages are also controlled independently similar to the simulation results. Thanks to the model developed, the overall structure of the system has been simplified and thus its applicability has been increased because fewer components were used in the design and also high voltage gain was provided.
