    Work Experience

    Design and Development Engineer at ASP Equipment

    15/09/2013 – On going

    Development of power converters for Aerospace applications. Definition of specifications, design according to specifications, verification and validation through prototyping, circuits test.

    Young Graduate Trainee at ESA Power & Energy Conversion Division

    01/09/2012 – 31/08/2013

    Research on distributed power systems and development of an intermediate bus converter to split the energy conversion chain in two different stages. A theoretical study was carried out to identify when this architecture improves the overall efficiency given by a single stage converter and the features that this converter should have to maximize the overall efficiency. Afterwards some prototypes of the most promising options were built to validate the results.

    Research assistant at Power Electronics System Group (GSEP) of Universidad Carlos III de Madrid

    01/11/2011 – 31/08/2012

    Research and design of different control architectures for distributed DC-DC converters for train applications. Modelling of the distributed system.

    Intern at Siemens Energy Distribution Business

    31/01/2011 – 30/09/2011

    Bids for medium voltage switchgears in energy distribution projects. Technical support for proposals and reviews. Follow-up projects and orders.

    Private teacher (self-employed)

    01/01/2007 – 31/07/2012

    Groups and individual lessons.

    Shop assistant at H&M

    01/06/2005 – 31/12/2007

    Customer assistance. Daily planning. Warehouse organisation.

    Education and training

    Industrial Engineering in Electronics and Automation at Universidad Carlos III de Madrid

    01/09/2005 – 01/10/2011

    Five years degree with solid background in Mechanics, Electrical systems, Energy Technologies, Thermal Engineering and Industrial Business and Management apart from Electronics and Automation which is the intensification that I chose. Most relevant courses: two modules of Analog Electronics (fundamentals of semiconductors, amplifiers, frequency analysis,  stability, negative feedback, oscillators, filters), two modules of Digital Electronics (logic gates, memories, finite state machines, microcontrollers) , Electronic Instrumentation (signal conditioning, modulation and demodulation, data acquisition and conversion systems, transducers), Power Electronics (DC-DC, AC-AC, inverters, rectifiers, control of power converters), three modules of Industrial Electrical Systems (magnetics, transformers, electrical machines, electrical systems), several modules of control engineering and automation (dynamic modelling systems, stability, control systems) and finally several modules of automation and electronics laboratory.

    My undergraduate thesis was carried out at GSEP with the title of DC-DC converter for micro-satellites electric thrusters. This converter was intended to adapt the low voltage energy produced by the solar array to a high DC voltage demanded by the electric thruster. The most prominent features of this converter are its high voltage gain and low power. This work comprised of an initial research on the state of the art, a theoretical study accompanied by simulations, design and an open loop prototype.

    Technical Skills

    ·         Electrical software: PSIM, PSpice

    ·         Mapple, Mathcad, Matlab, Simulink

    ·         Programming languages: Assembler, C, Fortran, Pascal, PLC and robots languages, real time libraries for C

    ·         Technical skills description gained through projects:

    ·         Power converters modelling: It was one of the main topics that I covered during my job as research assistant at GSEP. I gained a valuable experience modelling dynamic systems and I learnt about the difficulties involving distributed systems, especially regarding stability of Input Series Output Parallel systems.

    ·         Power converters analysis and design: Through the experience gained during the development of my undergraduate thesis, the experience at ESA and my current work at ASP, I strengthened my knowledge about power converters and acquired a global view of the design process: trade-off, specifications, detailed design, component selection, integration, manufacturing and test.

    ·         PCB: I designed the PCB for my undergraduate thesis prototype. Along my experience at ESA I developed several prototypes including PCBs.

    ·         Laboratory test and equipment: Test bench, sources, oscilloscopes, impedance analyser, soldering stations. Seminar on Design for testability.

    ·         Control system: I designed and simulated control systems during my experience at GSEP and ASP.
