Application of a boost based multi-input single-output DC/DC converter

Design and application of a multi-input single-output (MISO) dc/dc power converter is presented that provides the interoperability of separate energy sources having different power levels those are connected to the same dc bus through a double-layer boost converter. Thus, power control of the proposed MISO converter is realized on both the negative and the positive layers. As the first step, mathematical model and state equations of the converter are created and then verified in Matlab/Simulink. Control of the power flow and the output voltage is achieved by setting the duty cycles of switches located on each layer. A PI controller is added to the model to optimally perform the voltage and load sharing control. Furthermore, a real prototype of the proposed MISO converter is carried out to verify the simulation results. Experimental results show that the proposed MISO converter is a powerful solution for hybrid energy systems consisting ofdifferent kind ofenergy sources.
