New modular backplane standard for space applications is based on commercial standard. When adapting for space some gap of usability is identified. At module level a gap in the power supply is identified between the commercial standard and the space application when failure handling is considered. The gap at the input of the module power supply is the need of current limitation and voltage protection. Since this is common block used in all modules, an efficient solution from all perspectives are extremely important.

Thesis description

Object of this master thesis is to develop a high efficient solution for first step conversion taking care of the module current limit protection and voltage limitation
Included is to find concept for achiveing both high efficiency and small board area of the conversion step. Such as magnetic design, use of GaN fets and unregulated output to be investigated.

The work is a master of science thesis project of 30 credit points and the duration is 20 weeks for two students.

Proposed starting time is in January 2021, but it is possible to start earlier. Starting time will be decided in agreement with the students.
