Generate, store, distribute and control — the subsystem that causes a quarter of all on-orbit failures
Electrical Power Subsystem
Three sessions: EPS fundamentals, the design process with real sizing arithmetic, and the hardware development flow from SPICE to a PC/104 board.

What you will be able to do
- Size a solar array and a battery from mission parameters
- Build a power budget across operating modes and defend the margins
- Choose between peak power tracking and direct energy transfer, with reasons
- Explain the unloading function and why its absence is unrecoverable

Syllabus
Module 1
EPS fundamentals
What the subsystem is for, what it is made of, and why it fails.
Module 2
The design process
Beta angle, eclipse fraction, power budgets, and the sizing procedures.
Module 3
Building the board
From mathematical design to a manufactured PC/104 card.
Assessment
