Satellite electrical power system (EPS)

Block diagram

Overview

Satellites harness power from solar panels to power spacecrafts. This high-voltage supply needs to be stored and converted for all the onboard electronics. Our large portfolio of space-qualified devices and reference designs help you maximize your system performance.

Design requirements

Modern satellite electrical power systems (EPS) require:

  • Multiple low noise and efficient point-of-load supplies.
  • Efficient isolated power supplies to convert the main bus to point-of-load supplies.
  • A feedback method to monitor the secondary supply rail.
