DC Transformer based on DC-DC converter

DC Transformer based on DC-DC converter

The goal of this project is to find a solution for an efficient and light energy processing DC-DC converter for future weight-critical transport applications. This will be achieved by the means of a novel and optimized Air Core Solid State Transformer (SST).SST is a component which has been the key enabler of DC power

grid paradigm, as it integrates energy conversion and galvanicisolation into a single device. In conservative designs, the galvanicisolation is obtained through a bulky low frequency transformermade of iron and copper and this project will develop a novelsolution, a novel energy processing component, that omitsemployment of such an element as magnetic core, consequentlydecreasing the weight of transport vehicles (airplanes, ships,trains), and its CO2 footprint.The student will have to analyze different possible topological

solutions, research the impact of the latest semiconductortechnology (SiC and GaN) and perform a theoretical design of thedescribed DC-DC converter.

Digital Twinning of a Power Converter

The latest trend in industry is to build systems that will help itnot only during the conceptualization, prototyping, testing anddesign optimization phase, but also during the operation phasewith the ultimate aim to use them throughout the wholeproduct life cycle and even beyond. The fact that we have a real-time availability of data is opening up new opportunities formonitoring, improving operations throughout the life cycle of aproduct and improve design decisions. The main driver for thisnew design and maintenance paradigm is Digital Twintechnology.The proposed activity is under the umbrella of an internationalconsortium lead by Infienon and Fagor, among the others.

WiBatt – Develop of an intelligent Synchronization module for Wireless Power Transfer system

Wireless charging of electric vehicles has significant advantages over conventional wired charging. However, since transmitter and receiver must work separately and the communication between primary and secondary is very difficult, the use of diodes in secondary is mandatory. This lowers the efficiency drastically.

The objective of this project is to develop an intelligent module that allow the use of SiC MOSFET in secondary to improve the efficiency. This module needs to measure the magnetic field from the primary to be able to synchronize the secondary rectifier.

Automated Side Channel Attack Protection of Digital hardware Accelerators

Hackers use side-channel information such as the power consumed by a circuit or the electromagnetic noise emitted during the execution of logic gates while dealing with important data, such as cryptographic operation with hidden keys. With no protection, guessing a key using this mechanism is quite easy. The goal is to protect circuits by a technique call dual rail, which (see figure) generates a false signal that compensates the activity of the real circuit. In this TFG/TFM, the proposed plan is the following:- Develop a HW accelerator of a cryptographic block- Learn on how to attack it (oscilloscope, antenna and Matlab)- Develop the protection mechanism (digital design)- Measure how difficult is to attack

again, and compute the effectiveness- Try to generalize the technique to

any circuit, developing an automated tool.

Un-terminated frequency response measurement for small-signal blackbox characterization of dc-dc converters

Blackbox characterization of commercial dc-dc converters is importantfor control designs, stability analysis, etc. Besides, these models can beinterconnected in series or parallel to build power electronic distributionsystems.This project aims to obtain a small-signal behavioral model of aconverter from its frequency response. To that end, the input and outputterminals of the converter must be perturbed with a frequency analyzerand a power amplifier while the converter is working in a specificoperating point. As the measured signals obtained will be coupled withthe impedances of the sources and load employed, the “un-terminated”response must be inferred.

Nonlinear characterization of DC-DC converters based on measurements for microgrid applications

The integration of commercial dc-dc converters in power supplyarchitectures, such as microgrids, can be a difficult task due to thedynamic interaction among the converters. Besides, in some applicationswhere the operating conditions are highly variable, the converters canshow nonlinear responses, which limit the use of small-signal models.This project aims to develop a methodology to obtain behavioral modelsof commercial converters with nonlinear behaviors based onmeasurements of their response to specific perturbances. The modelsobtained can be of great value in order to perform system-level analysisand designs of microgrids.
