Presentation

The University of Valencia and the company Würth Elektronik eiSos have created an institutional Chair or Cátedra to promote education and research on Electromagnetic Compatibility (EMC).

One of the key objectives of the new institutional chair for electromagnetic compatibility is to encourage both research into this technology and its practical application.

Furthermore, within the activities of the Cátedra promotes the developing of PhDs and Master and Degree Final Projects, seminars and courses on EMC topics, and attendance to international Conferences. Every year, the company propose some projects to offer several internships in the Cátedra Laboratory and Würth Elektronik headquarter. These tasks are managed by the Cátedra Director José Torres, Professor of the University of Valencia, and Jorge Victoria, Product Manager of EMC components in the German company.

EMI IN OUTPUT/INPUT CONNECTORS

Motivation

Connectors suffer from many EMC problems due to they can be considered as short length conductors with a rigid body. Sometimes it is difficult that manufacturers ensure a 360º shielding in the connectors because it depends on the many factors such as case shielding, number of grounded pins or spring length.

DEVELOPING OF MODELS AND NEW TECHNOLOGIES FOR SMART GRIDS COMPATIBLE WITH THE 2-150KHz SPECTRAL BAND

Smart grids are energy networks that can automatically monitor energy flows and adjust to changes in energy supply and demand accordingly. Thereby, on the basis of research literature, the Smart Grid can be described as a power system possessing specific possibilities and characteristics such as the integration of a greater amount of energy from renewable energy sources or activation of end-users role in Smart Grids in order to they can be both consumers and producers of electric energy—so-called ‘‘prosumers’’.

The main benefits that can be gained by means of the implementation of Smart Grid technologies are reduction in CO2 emission, the improvement of the voltage profile and local balancing of electricity production and demand and higher efficiency of electricity management, among others. The technical realization of these benefits in Smart Grids is based on the application of modern measurement based on Smart Metering and control systems. This device provides the first benefits of the Smart Grid to customers by empowering it to understand and reduce their energy use and monthly costs. Smart Meters are the gateway to increased energy efficiency and integrated renewable energy sources, while supporting a new generation of intelligent appliances that will benefit customers.

Nevertheless, Smart Meters are finding a lot of problems in terms of measurement and communication from a power quality viewpoint. It is due to there are a huge number of equipment and devices such as LEDs and PV installations connected to the grid which produce waveform distortion. Despite all the existing regulations, there is a lack of standardized tests and a lack of knowledge on emission, immunity, and compatibility in the frequency range 2 to 150 kHz. In those cases that standard tests exist, the equipment is tested one at a time and in a controlled environment that can differ a lot from the environment that equipment meets when connected in an actual installation. When setting new standards for low voltage equipment it is essential that they are based on realistic conditions. For that reason it is important to do measurements not only in completely controlled environments but also in situ.</p

Therefore, it is necessary to evaluate the performance of the devices connected to the grid in order to ensure that they are working properly and they are not concerned by EMC problems in real surroundings. This research is focused on carrying out a specific study about developing measurement methods, to identify interference models, and to improve Electromagnetic Compatibility testing for metering, communications devices and other systems deployed in Smart Grid environments.

Final Master Project (TFM) – Master’s Degree in Electronics Engineering

CHARACTERIZATION OF ELECTROMAGNETIC NOISE SUPPRESSION SHEETS FOR EMC APPLICATIONS

This Electronics Master’s Project is focused on characterizing several kinds of Noise Suppression Sheets (NSS) and studying their performance in some applications. Thereby, some set-ups will be designed and implemented in order to analyze and evaluate behavior of these materials in electronics circuits or systems with Electromagnetic Compatibility (EMC) problems. NSS can be an innovative and interesting solution to reduce or suppress high frequency electromagnetic noise which may generate Electromagnetic Interferences (EMI). This solution is based on absorption materials characterized by the permeability parameter, however, another elements should take into account such as sheet thickness, size, shape and composition. Therefore, the main objective of this project is determining the absorption capability of NSS to reduce electromagnetic noise through proposing some measuring methods.

Final Degree Project (TFG) – Degree in Telecommunications Electronic Engineering

ELECTROMAGNETIC SHIELDING TESTING THROUGH WIRELESS POWER AND SHIELDED ENCLOSURE EXPERIMENTS

The objective of this project is the designing and building of two Electromagnetic Compatibility (EMC) experiments in order to generate conducted and radiated emissions. With these designs, the next step is to test several sorts of electromagnetic shielding materials provided by Würth Elektronik.
The first experiment consist of a Wireless Power circuit with a simple design so that it can be easily built to test noise suppression sheets in a way that the electromagnetic field generated by the circuit can be redirected and concentrated to the receiver.
The second experiment is a shielded enclosure system which can generate some emissions problems, radiated and conducted both, with aiming to find those problems and measure them, to propose and studying several solutions to reduce those emissions.
