“…Lack of sufficient area for installation, low sunshine, shades of trees and tall buildings are some of the biggest threats affecting their performances [9,10]. Therefore, PV per voltage generation tends to be low in nature which is why the power converter technology is much-needed [5], [11,12]. This technology can be used to step up the low DC voltage generated by the PV panel into the desired output value [13,14].…”

Background The demands for clean energy is growing rapidly and the fossil fuel we use in our everyday live is ushered in CO2 and other greenhouse effects, resulting in natural disasters and other climate threats. To continue on this route, the world is challenged to prepare for the unknown disasters. Hence, the search for a clean, alternative energy resource, which could bring resilience back to our cities is in incredibly rapid velocity. Solar energy is a clean and alternative energy that can be use but PV panels tend to generate low energy in nature which is why a lot of panels have to be employed in order to go off-grid. A simple DC-DC converter can be used to boost the energy generated by PV panels. Provided herein is an extended DC-DC single ended primary inductor converter (SEPIC) for micro-grid based photovoltaic (PV) applications. The new topology was designed with an addition of some components to the conventional SEPIC. Results The extended SEPIC topology utilizes a single power switch with high voltage gain, low duty-cycle, reduced voltage stress across the power switch, low density and cheap. The new topology was designed with an addition of some components to the conventional SEPIC. A 125 V DC output was generated from a 12 V DC input through MATLAB/SIMULINK. The new SEPIC converter revealed the best value voltage gain as 10.42, duty-cycle value of 0.8 and voltage stress of 62.5 V compared to the conventional SEPIC or SEPIC integrated with other converters. Conclusions the results of voltage gain, duty-cycle and voltage stress obtained validate the credibility of the new converter and show the potentiality of the converter for the adoption in power step-up applications.

“…The DC-DC power converters are of many types, transformerless and those with transformers [11]. The transformer types were deemed too expensive and higher voltage gain can be attained by two things, turn-ratio and duty-cycle of the transformer [10].…”

“…Today's global energy stock primarily comes from fossil fuels such as coal, oil and natural gas which was key sources of greenhouse fumes. The Earth's climate will be compromised if Solar energy is one of the most underutilized among them, the experimenting the solar panels and photovoltaic cell are extremely important, This implies that solar photovoltaic (PV) has a great capacity for a variable energy economy, and the further development of PV panels technology becomes very critical for it to become a major electricity and energy resources [7]. One of the predominant element of solar panels is having low dc power which is not suitable for direct utilization by inverters [12].…”

“…In a photovoltaic (PV) system, the most visible part of the system is the PV panels. Panels can be mounted in open fields and building rooftops, and nowadays, PV cells are being integrated into the building materials themselves [7]. The PV cells convert solar energy into electric energyIn order to overcome potential instability issues, recent research has begun to focus on making the PV system more intelligent unit.…”

Solar energy resourses is abundantly available but its exploitation through PV system is not economically feasible. In order to optimize the power output, an electronics device should be integrated with solar PV system. A high classical classical single ended primary inductor converter SEPIC converter for renewable energy applications was designed, constructed and experimentally tested. The voltage multiplier cell (consists of two diodes and two capacitors) was incorporated with SEPIC to design a DC – DC boost converter for PV application. The new converter can improve the capacity of 10 V DC input to output 60 V DC, the design circuit will boost input voltage and maintain a constant voltage output. The performance of the proposed topology was authenticated and the result achieved from the implemented prototype are in good agreement with the design strategies. The effects of input parameters such as sun radiation and useful power input on PV system and DC-DC converter outputs were investigated. Results comfirmed that the DC-DC converter was perfectly designed using Multisim software and accurately constructed, when integrated with solar PV system under no load and on load conditions.
