Abstract/Summary
Making use of renewable energy directly from the location of production requires converting source power into usable power. The specific scope of this project focuses on the DC to DC conversion within a user friendly universal farmbot system. Since renewable sources vary widely in voltage and current, a wide input-range DC to DC converter is desired. Physical isolation, long lifespan, and adverse weather requires safe and reliable final product specifications. The goal of a very wide customer base drives the need for a product that does not require tinkering to get working, but to be usable out of the box for a vast majority of energy sources. This project designs, purely through simulation due to COVID-19 pandemic, a Universal Input Module (UIM) DC-DC converter, which acts as the first step from the energy source to the usable power bus. UIMs can be connected in parallel to effectively make a Multiple Input Single Output (MISO) system. The main component of conversion is a 4-switch buck-boost controller. Input filtering, output filtering, parallel function, and two theoretical renewable inputs are incorporated to give the simulated converter as realistic of a function as possible. The selection process for all main components, surrounding components, and equivalent simulation circuits is included. With use of LTSpice, the simulation results meet the customer’s specifications.
