At present, power transmission systems are moving to renewable sources because their features more reliable, easy install, increase public health, and lower development costs when associated with conventional energy systems. Here, solar technology is considered of its advantages equated other free production, good density, low air pollutants, less maintenance requirement. In this article, a triple diode cell for achieving the accurate voltage PV, production increased by proposing Adjustable Cuckoo Search Methodology (ACSM). ACSM studied comparing it swarm Maximum Power Point Tracking (MPPT) methodologies. The proposed MPPT controller tracks MPP 0.025 s time duration at 355 K. Finally, one-switch non-isolated improvement DC-DC circuit used in system giving wide gain consumer loads. ACSM-fed converter investigated utilizing MATLAB/Simulink tool experimentally applying programmable source.
