Master Thesis: Power-Level Optimization for Energy Saving in Testing Laboratory

Stockholm, Stockholm, Sweden

What you will do:

• Measure baseline energy use across representative test campaigns, including setup, active testing, idle, standby and shutdown.
• Map consumption across major contributors such as radio units, power amplifiers, signal generators, analyzers, automation servers, cooling and auxiliary equipment.
• Study how RF output power, equipment operating point and test duration affect total energy use per test.
• Develop and assess practical optimization measures, such as improved test sequencing, automatic standby, controlled power-up and power-down, reduced idle time, equipment sharing and cooling set-point adjustments.
• Compare baseline and optimized test campaigns, checking energy use alongside measurement uncertainty, repeatability, requirement coverage and defect-detection capability.
• Quantify energy use per test and campaign, peak and average power demand, idle-period savings, equipment utilization, and estimated annual energy, cost and carbon-emission reductions.
• Recommend improvements to automation, laboratory procedures and future test setups, while respecting warm-up requirements, thermal limits, calibration conditions, safety rules and RPV specifications.

The skills you bring:

• You are currently pursuing a master’s degree in electrical engineering, energy systems, sustainable energy, mechanical engineering, automation, applied physics or a related field.
• You are interested in energy efficiency, measurement and data analysis, laboratory systems, radio-frequency testing or power management.
• Experience with energy monitoring, electrical power measurements, RF equipment, RPV testing, laboratory automation, scripting or data analysis is a plus.
• Familiarity with cooling systems, equipment operating limits, test repeatability or verification requirements is a plus.
