Design of an ultra flat power supply for future slim TFT/LED displays

Next generation TFT and LED displays need to have a slim design to fit the space and design of the train interior. As the power supply is one of the dominant factors to define the thickness of the display, there is a need of a cost effective ultra flat galvanic isolated power supply.

The power supply will need to be stable under all conditions (closed loop) and will need to be compliant with the railway standard with regards to input voltage conditions, EMC, thermal behavior,... which will make the design very challenging.

The thesis should include the following phases

• Requirement definition based on Televic products (power, budget, ...)
• Architecture definition based on technology study and existing examples
• Component selection (low profile planar transformer, filters, switching converter,...)
• Spice simulations
• Measurement & study of a devkit
• Schematic design and Layout
• Prototyping
• Board verification
• Environmental testing (thermal, EMC, ...)

The student will have the opportunity to go through the complete development phase of an electronic design, discuss with senior engineers, align with component manufactures and distributors
