Partial Power Converters for DC-DC Applications
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2023)
This thesis studies partial power processing (PPP) based architectures for DC-DC applications. This type of solutions aim to reduce the power processed by the power converter. This way, the power losses and the volume of ...
Control of interlinking converters for hybrid AC/DC power systems
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2023)
Electrical power plays a very important role in today’s society, but the necessity to reduce the greenhouse gas emissions requires to shift the classical fossil fuel-based power generation towards a renewable based model. ...
Microstructural evolution analysis during the near solidus forming process: the case of AISI 316
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2023)
The current trend in manufacturing processes aims for the reduction of steps and the decrease of raw material used. In order to achieve this with high melting point alloys such as steels, a new process was defined under ...
Effect of Post-Processing Treatment on Fatigue Performance of Ti6Al4V Alloy Manufactured by Laser Powder Bed Fusion
(MDPI, 2023)
Fatigue properties of parts are of particular concern for safety-critical structures. It is well-known that discontinuities in shape or non-uniformities in materials are frequently a potential nucleus of fatigue failure. ...
Zientziak bizidunontzat: Tokiko curriculumak Euskal Herri osasuntsurako hezkuntzan
