Investigations of high efficiency DC DC converter for PV applications

Abstract

The temperature of the earth is steadily rising as a result of newlineexcessive consumption of fossil fuels that cause global warming. In addition to newlineimpacting global economic stability, the depletion of fossil fuel resources is newlinealso exacerbating the challenge of rising prices worldwide. Governments all newlineacross the world are making numerous attempts to investigate alternative newlineenergy sources and reduce pollution. One of the largest and most rapidly newlineexpanding sources of renewable energy for the production of electrical power newlineis the Photovoltaic (PV) generation system. The PV system is one of the newlinerenewable energy systems (RES) which is proven to be the simplest and most newlineefficient energy generation system with high potential benefits. newlinePV is regarded as one of the growing technology across the domain. newlineIt is necessary to analyse how well the PV systems interact with the assigned newlinepower converters, voltage controller and load. The specialized diodes found in newlinephotovoltaic cells convert the incident solar energy directly into DC voltage. newlineThe acquired DC voltage falls short of the required standard and is insufficient newlineto meet the energy demand, thereby necessitating the use of DC-DC converters newlineto elevate the obtained voltage to the anticipated level. Generally, DC voltage newlineobtained by PV panel is unstable because it is susceptible to frequent newlinetemperature variation, shadows, changes in environmental conditions, etc., newlineeven the environmental pollution affects the PV output. So as to regulate the newlineoutput of PV, an efficient DC-DC converter is utilized. The converter collects newlineunstable voltage from the Photovoltaic panel and converts it into stable newlineoptimized dc voltage which is capable of energizing the load. newline
