A switched-inductor model for a non-isolated multilevel boost converter

This paper discusses a switched inductor design for a non-isolated multilevel boost converter. A Non-isolated proposed multilevel boost converter is suitable to provide a high conversion ratio which essentially benefits renewable energy systems. In addition to the voltage stress reduction, the proposed switched inductor MBC has shown an improvement in voltage gain. The new switched inductor model has been inserted as an input into the multilevel boost converter. The proposed converter consists of 2N-1 capacitors, 4N-1 diodes, three inductors and a single switch. The proposed model is a three-level boost converter which is supplied by 12 V to produce 280 V at a 50 KHz switching frequency. A MATLAB/SIMULINK simulator was used to evaluate and test the proposed switched inductor model.
