Master Thesis, 30 HP: ”Electrical Power Management in Aircraft Systems”

Huskvarna, Sweden
Closing date: 30 March 2023

Students interested in power electronics – here is a Master Thesis for you - aiming for the next generation of power management systems in aircrafts!

Your role


Already today, a lot of equipment is electric powered in aircrafts. In the future, the electric powered equipment will increase and include high power consumers. Next generation of aircrafts will most probably have a DC power supply of 270 VDC or higher. The power supply will include battery and maybe super capacitors to cover the need of high power peaks. At Saab we plan for some new products within the next generation of power management system, and therefore we want to increase our knowledge in this area.

Description of the master thesis

This Master Thesis aims at studying a power management system. The system includes generator, battery, capacitor, high/low voltage transformation and loads. The system can be simulated in Matlab/Simulink or build-up by hardware depending on interest.

Possible ways of study this power management system are:

  • Energy storage management, e.g. electrical architectures, battery/super capacitors cell status  and cooling needs
  • Load distribution control and protection, e.g. for capacitive loads, inductive load opening and short circuits
  • Monitoring functions, e.g. status, warnings and maintenance information

The work will include:

  • Study the theory of power management system and redundant power management system
  • Design a power management system
  • Test/simulate the system behavior and/or performance
  • Identify critical areas for general power management system
  • Report

Your profile

This Master Thesis is suitable for 1-2 student with interest in analog and power electronics.

You are at the end of your technical master education in Engineering Physics, Electrical Engineering, or equivalent, and about to start your Master Thesis work for 30 HP.

This position requires that you pass a security vetting based on the current regulations around/of security protection. For positions requiring security clearance additional obligations on citizenship may apply.
