This engineering research report investigates potential improvements to DC house connections as replacements for AC power sources, particularly focusing on renewable energy integration. The literature review highlights the shift towards renewable energy due to the depletion of fossil fuels and the advantages of DC power in reducing energy losses associated with AC conversion. The research explores the use of LED lighting systems in DC houses, emphasizing their efficiency and compatibility with DC power. A proposed expansion involves incorporating flashlight adapters to enhance the functionality of DC houses, especially in remote areas. The project aims to design, test, and implement a portable light system for DC houses, incorporating batteries for portability and using DC-DC converters for efficient charging. The methodology involves a quantitative approach, comparing DC and AC houses based on light brightness and duration, along with qualitative analysis of existing power sources. The research ultimately seeks to optimize DC house designs for improved performance and cost-effectiveness.
