A New Multilevel Inverter Topology For High Step Up DC-DC Converter

G Aruna, D Srinivas Rao


High step up proportion dc–dc converters with megawatt evaluations are of enthusiasm for wind turbine interfaces and high-voltage direct current frameworks. This paper introduces a secluded multilevel dc–dc converter in view of the standard boost converter topology yet with the typical single switches supplanted by various capacitor-cinched sub modules. The converter is worked in resounding mode with reverberation between sub module capacitors and the arm inductor. A phase-shifted switching  course of action is connected with the end goal that there is a consistent number, i.e., N, of sub modules supporting the high voltage at once. In this operation mode, the progression up proportion is reliant on the quantity of sub modules and the inductor charging proportion. The converter shows versatility without utilizing a transformer and is equipped for bidirectional power stream. This venture is reached out to next sub module for expanding working scope of the converter. The outcomes checked through MATLAB/SIMULINK condition.
