Ing. Rastislav Havrila – Personality of Science and Technology


Ing. Rastislav Havrila – Personality of Science and Technology

Awarded Ing. Rastislav Havrila, PhD., is an expert in the area of electrical engineering, automation and control systems – electric drives and power electronics, from the Electronical Research and Projecting Company Nová Dubnica, (EVPÚ), j.s.c., Nová Dubnica.

The culmination of the Week of Science and Technology in Slovakia is the awarding of awards for work and achievements in the area of science and technology. The awards ceremony took place on 10 November 2016 at 7PM in the INCHEBA Expo in Bratislava. The Award for Science and Technology in five categories (Personality of Science and Technology, Lifelong Achievements in Science and Technology, Personality of Science and Technology Under 35 Years Old, Populariser of Science, and Scientific and Technical Team of the Year) were given by the Minister of Education, Science, Research and Sport of the Slovak Republic Peter Plavčan, who is the patron of the event. The Award for Science and Technology has been awarded since 2014, replacing the award of the Minister of Education, Science, Research and Sport of the Slovak Republic. The objective of this transformation is to increase the social prestige of the awards for science and technology.

Ing. Rastislav Havrila, PhD., was awarded the Award for Science and Technology in the category Personality of Science and Technology.  Proponent: Association of Research and Development Industrial Organisations.

Ing. Rastislav Havrila, PhD. (1974), was born in Strážske. Between 1992 – 1997, he studied Electrical Engineering: Heavy Current at the Faculty of Electrical Engineering of the University of Žilina. Since 2004, he is the director of the R&D Department at the Electronical Research and Projecting Company Nová Dubnica, j.s.c. He is actively working in the field of power electronics and he is putting emphasis on the full implementation of results achieved in addressing R&D projects into designing and realisation of industrial installations. In designing and realisation of new products, he utilises the most advanced device-optimised technologies, including the selection of appropriate power components.

In the long term, he is working on problematics of static power converters, while the subject of his R&D activities are circuit diagrams, design of control algorithms, system simulation and design of software with a view to applying the findings in industrial installations. In addition to standard converters, he witnessed the realisation of power supplies for magnets of particle accelerators, converters for transport equipment and special trackpoints. He is working on a number of projects with grant support from several agencies, and he is the author and co-author of several patents and scientific publications, which are being cited. Through the implementation of his unique algorithms into microcomputer control structures, we can see an increase of technical parameters in converters and improvement of parameters related to electromagnetic compatibility, while reducing costs throughout their life cycle. Several proposed solutions are the subject of industrial property protection.

We interviewed Ing. Rastislav Havrila, PhD.

M. BARTOŠOVIČOVÁ: You are among the top three awarded the Award for Science and Technology in the category Personality of Science and Technology. What does this mean to you?

R. HAVRILA: "This award confirms that a specific long-term work has a meaning and in some exceptional cases, the wider community notices it and appreciates it. I appreciate it and I believe that the Ministry of Education, Science, Research and Sport of the Slovak Republic will continue in this tradition and motivate scientists and researchers, also in this way, in their creative, but sometimes unappreciated work."

Ing. Rastislav Havrila

M. B.: You have received this award for the results achieved in addressing and managing R&D projects in the field of power electronics and static power converters with unique implementation outputs in a number of industrial installations. Could you at least briefly explain your work?

R. HAVRILA: "Our company is working on R&D of installations in areas, which are not in major commercial stream. These concern the development of special systems, which require a large amount of work focused on the analysis of solutions and the design of unique structures and typologies, while the serial production on a larger scale is unlikely. An example of such installations is power supplies for particle accelerators. These are, same as the particle accelerator, designed to measure, while we are working with superconducting magnets as load for our installations and the energy is in dynamic regimes stored in supercapacitors. Another area of our interest is transport - rail transport in particular. We have become the standard manufacturer and supplier of auxiliary converters for railcars and in recent years, we have been working intensively in the area of modern traction drives. Of course, we also have activities in other areas of electrical engineering industry."

M. B.: What is their main contribution?

R. HAVRILA: "In case of sources for particle accelerators, their contribution is probably clear. They enable the research in particle physics, helping push the boundaries of our knowledge. Other installations that are the subject of our development are modern systems with minimised energy consumption, high reliability, and optimised operating costs. In case of converters for railcars, for example, they help improving safety, comfort and travel culture. In economic terms, these are installations with high added value. In their production, we employ a number of other workers not only in our company, but also in the surrounding area."

M. B.: What are you working on now?

R. HAVRILA: "Currently, an upgrade of information systems is underway in our company, so I focus on optimising the management process of the development documentation and its transformation from technology into production. In the test phase, we have a complete electrical equipment of a multi-system locomotive. My colleagues have received an award for this project in the category Scientific and Technology Team of Year. At present, however, we are paving the way for repeated production."

M. B.: What would you like to deal with in your next research?

R. HAVRILA: "The area of static power converters is a dynamic field of electrical engineering industry. The introduction of digital control systems significantly improved the possibilities for customer support during their entire life cycle. We will continue the development of monitoring and diagnostic systems of our installations with a focus on remote diagnostics, using either an Ethernet connection or a wireless data transmission. In the near future, we will also begin the development and construction of a prototype with new components based on silicon carbide (SiC). This is not a totally new technology, but in the area of our power and voltage interest, there is only a few manufactures worldwide who already apply it in their products. Like all new technologies, this one also shows signs of increased costs, but we assume that the costs will get to an acceptable level once the production increases. By implementing these elements, we expect further increase in efficiency and reduction in the size and weight of our installations. Considering this is the introduction of new technology, I expect a large scope of work also in collaborative systems, whether in excitation or control circuits."

M. B.: Thank you for the interview. On behalf of the editorial staff, I congratulate you for the award and wish you many more success.
