Purpose of Document

Complete review of the EPS board version 1.

Version history: Started when I started the position so Nov 2024. Solely to analyze what the design was regardless of its issues.

High-Level Overview

This is the general overview of the system.

2024EDR_BlockDiagram.png

There are four main sections of the system:

  1. Generation - manages the power coming from the solar panels
  2. Storage - manages the batteries
  3. Distribution - shares the power collected with the rest of the satellite
  4. Logic - controls what power source to use, when to charge, etc.

Generation

Component Overview
Solar panels Gathers energy from the sun 😎
Solar panel protection Protects against reverse, short current, overvoltage
“Voltage regulator” MPPC Regulates output voltages of the solar panels
Load sharing component Takes in 3 sources and combines them to create 1 source/output

Why did we put them connect the solar panels as we did? What is our reasoning behind the configuration?
