A NOVEL HIGH GAIN CUK INTEGRATED SEPIC CONVERTER GWO APPROACH FOR DC MICROGRID APPLICATIONS

R.MANIKANDAN*, S.SUMATHI

Abstract

An better DC-DC converter is proposed in this mission, based totally at the aggregate of the Cuk and SEPIC converters, that is properly-proper for solar photovoltaic (PV) packages. The converter uses most effective one transfer (that's ground-referenced, so easy gate drive circuitry may be used), but offers twin outputs in the shape of a bipolar DC bus. The bipolar output from the DC-DC converter is capable of ship power to the load, and leakage currents can be eliminated if the latter kind is used without the usage of lossy DC capacitors in the load present day loop. The proposed converter makes use of integrated magnetic cores to couple the output inductors and GWO algorithm, which notably reduces the input modern-day ripple and for this reason significantly improves the electricity extracted from the sun PV gadget. The design method in conjunction with simulation, waveforms, and efficiency measurements of a DC-DC converter are offered to show the idea of the proposed converter.
