Using a SEPIC Convertor to Improve the Efficiency of Modern EVS

Chetan Khemraj, Sushma Barahate

Abstract


In the future, solar (photovoltaic energy) is a promising alternative electrical energy source. Solar panels aren't very effective these days, converting sunlight to electricity at just about 12-20 percent efficiency. Other factors, such as the temperature of the solar panels and the load conditions, could affect efficiency even more. Because photovoltaic (PV) cells have nonlinear behavior, dc-dc power converters are required to match the load to the solar modules. When compared to a buck boost converter, an efficient photovoltaic model using Single-Ended Primary-Inductor Converter (SEPIC) extracts higher efficiency (ignoring EMI electromagnetic interference and current stress). To fix the range, use line difference and load difference to design the SEPIC converter, as well as irradiation and temperature graphs to design the solar panel module. The Single-Ended Primary-Inductor Converter was used to calculate the PV array's efficiency (SEPIC). The setup is intended to be utilized in the electric car hub motor for motor operation. With today's sky-high fuel prices, it's become critical to explore for alternative energy sources for vehicles. Electric vehicles are the ideal alternative because they are pollution-free and do not rely on fossil fuels. As a result, it can help us save our foreign reserves while simultaneously reducing pollution in our already polluted cities. However, it has the disadvantage of running out of battery power. We focused on how to improve the efficiency of an electric car utilizing a revolutionary notion called SEPIC convertors in our study report. A detailed examination of how to boost the mileage of the specified electric vehicle was also conducted. Keywords—buck boost convertor, performance efficiency, single ended primary inductor converter, BLDC motor, Electric derive MPPT controller, PV system, solar cell.
