In recent years, there has been a rapidly growing need for sustainable energy sources. This need comes from the increasing threat of climate change, significant population growth, as well as the effort to bring electricity to rural and underdeveloped areas across the world. The DC House project at Cal Poly aims to address these issues. The Multiple Input Single Output (MISO) converter is an integral part of the DC House project. The MISO converter is a system that connects multiple power sources to a DC bus. This allows the DC House to be powered by multiple types of renewable energy sources, including solar power, wind power, hydro power, and human power. The MISO converter has a nominal input of 24V and a nominal output of 48V with a maximum power rating of 150W. Improvements can be made to the current low-cost MISO to increase efficiency and decrease costs. Several considerations that can be implemented include but are not limited to component selections, board size and layout, and more relaxed design constraints especially for those requirements that were met with significant margin. This project entails the second revision of the low-cost MISO Boost converter incorporating improvements as previously mentioned. Simulation results of the proposed design show that the proposed design meet all design requirements including reduced cost and physical size. Hardware implementation unfortunately did not take place due to the COVID-19 pandemic which caused campus shutdown and thus our inability to access the power electronics lab
