The doctor study programme is devoted to the preparation of the high quality scientific and research specialists in various branches of power electronics, control technology, design of electrical machines, electric power generation and distribution, and electric power utilization.
The aim is to provide the doctor education in all these particular branches to students educated in university magister study, to make deeper their theoretical knowledge, to give them also requisite special knowledge and practical skills and to teach them methods of scientific work.

The goal of the postgradual doctoral (PhD) study of the program "Power Systems and Power Electronics" is the education for scientific work in the area of power electrical engineering and power systems. Graduates of PhD find occupation either as scientific or research workers including industrial development, either as university teachers and in higher manager functions as well.

The graduate of the doctor study program "Power Systems and Power Electronics" obtains broad knowledge of subject of high power engineering. The knowledge is built mainly on theoretical background of the subject. Moreover, the graduate will obtain deep special knowledge aimed in direction of his/her thesis. The graduate will be able to perform scientific and/or applied research based on up to date theoretical knowledge. The graduate will be able to organize and lead a team of researchers in the studied subject.

Doctoral studies are carried out according to the individual study plan, which is prepared by the supervisor in the beginning of the study in cooperation with the doctoral student. The individual curriculum specifies all the duties determined in accordance with the BUT Study and Examination Rules, which the doctoral student must fulfill to successfully finish his studies. These responsibilities are time-bound throughout the study period, they are scored and fixed at fixed deadlines.
Students will write and pass tests of obligatory subject Exam in English before the state doctoral examination, compulsory elective courses in view of the focus of his dissertation, whereas at least two are selected from: Mathematical Modelling of Electrical Power Systems, New Trends and Technologies in Power System Generation, Selected problems from power electronics and electrical drives, Topical Issues of Electrical Machines and Apparatus), and at least two optional subjects (English for PhD students; Quoting in Scientific Practice; Resolving Innovation Assignments; Scientific Publishing from A to Z).
The student may enroll for the state doctoral exam only after all the tests prescribed by his / her individual study plan have been completed. Before the state doctoral exam, the student draws up a dissertation thesis describing in detail the aims of the thesis, a thorough evaluation of the state of knowledge in the area of the dissertation solved, or the characteristics of the methods it intends to apply in the solution.
The defense of the controversy that is opposed is part of the state doctoral exam. In the next part of the exam, the student must demonstrate deep theoretical and practical knowledge in the field of electrical engineering, electronics, electrical machines, and electrical apparatus. The state doctoral examination is in oral form and, in addition to the discussion on the dissertation thesis, it also consists of thematic areas related to compulsory and compulsory elective subjects.
To defend the dissertation, the student reports after the state doctoral examination and after fulfilling conditions for termination, such as participation in teaching, scientific and professional activity (creative activity) and at least a monthly study or work placement at a foreign institution or participation in an international creative project.

The doctoral studies of a student follow the Individual Study Plan (ISP), which is defined by the supervisor and the student at the beginning of the study period. The ISP is obligatory for the student, and specifies all duties being consistent with the Study and Examination Rules of BUT, which the student must successfully fulfill by the end of the study period. The duties are distributed throughout the whole study period, scored by credits/points and checked in defined dates. The current point evaluation of all activities of the student is summarized in the “Total point rating of doctoral student” document and is part of the ISP. At the beginning of the next study year the supervisor highlights eventual changes in ISP. By October, 15 of each study year the student submits the printed and signed ISP to Science Department of the faculty to check and archive.
Within the first four semesters the student passes the exams of compulsory, optional-specialized and/or optional-general courses to fulfill the score limit in Study area, and concurrently the student significantly deals with the study and analysis of the knowledge specific for the field defined by the dissertation thesis theme and also continuously deals with publishing these observations and own results. In the follow-up semesters the student focuses already more to the research and development that is linked to the dissertation thesis topic and to publishing the reached results and compilation of the dissertation thesis.
By the end of the second year of studies the student passes the Doctor State Exam, where the student proves the wide overview and deep knowledge in the field linked to the dissertation thesis topic. The student must apply for this exam by April, 30 in the second year of studies. Before the Doctor State Exam the student must successfully pass the exam from English language course.
In the third and fourth year of studies the student deals with the required research activities, publishes the reached results and compiles the dissertation thesis. As part of the study duties is also completing a study period at an abroad institution or participation on an international research project with results being published or presented in abroad or another form of direct participation of the student on an international cooperation activity, which must be proved by the date of submitting the dissertation thesis.
By the end of the winter term in the fourth year of study the students submit the elaborated dissertation thesis to the supervisor, who scores this elaborate. The final dissertation thesis is expected to be submitted by the student by the end of the fourth year of studies.
In full-time study form, during the study period the student is obliged to pass a pedagogical practice, i.e. participate in the education process. The participation of the student in the pedagogical activities is part of his/her research preparations. By the pedagogical practice the student gains experience in passing the knowledge and improves the presentation skills. The pedagogical practice load (exercises, laboratories, project supervision etc.) of the student is specified by the head of the department based on the agreement with the student’s supervisor. The duty of pedagogical practice does not apply to students-payers and combined study program students. The involvement of the student in the education process within the pedagogical practice is confirmed by the supervisor in the Information System of the university.

1. Charging stations for electric vehicles as an element of electricity system

   The urgent need for the development of charging stations for hybrid cars and electric vehicles (EV) still shows as important in the context of the current gradual development of this type of transport. The theme is focused on energy analysis of the concept of charging stations with integrated accumulation and renewable energy sources. Based on the concept will be developed the mathematical models. It will be performed energy-economic analysis in order to verify the possibility of using the concept in this way to reduce the load of the network at the connection point. Direct possibility of cooperation on concrete solution with an energy company is expected. The condition for successful defense of this work is to complete at least one month long internship at a foreign university.

2. Integrated Glare Metric for Various Lighting Applications

   Glare is a negative state of human vision that causes not only unpleasant feeling but also have negative influence on the performance of human vision system. For the glare evaluation there are many equations that are always used for specific application. For interior lighting systems it is used metric UGR. For glare evaluation caused by daylight from windows it is used metric DGP, DGI etc. However, there are disadvantages of these metrics. They are adapted for specific type of lighting system (e.g. offices, sport grounds, street lighting etc.) and specified for typical luminaires (e.g. luminaires with fluorescent lamps and opal diffusor, daylight windows etc.) However, they are all based on empirical data and therefore not on the physiological and psychological model. From this reason it is not possible to use these metrics to new aplications. This problem occurs especially in the current situation, where LED technologies started to dominate the market. The LEDs radiate from the very small surface and with the specific spectrum. The task of this thesis is to partially find answer to question: “What is the physiological and psychological mechanism that is responsible for unpleasant feelings caused by higher luminance”. On the basis of this mechanism the model of discomfort glare caused by high contrasts should be carried out. This model should be generalized and used in lighting systems. This topic is highly supported by international commission for illumination CIE and it is classed within the 10 strategic research goals in lighting technology.

1. The control of public lighting in Smart City

   This topic reflects current trends of the development of smart technologies in the area of human activities. Public lighting operations certainly belong in this group. The goals of this doctoral study are to research connections of night illuminaton problems with areas of visual sense, environment aspects, safety and power consumption. According to basic tasks in the area of Smart public lighting regulation of technical-photometric parameters of the luminaires is expected to be developed. Regulation should be dependent not only on time but also on the traffic density. Therefore, the direction of the research should lead for connection of above-mentioned areas and finding ideal equilibrium between them. It is expected to get those results with help of technical-photometric simulations, but also from practical objective and subjective testing, where evaluations should be carried out from data from at least 100 respondents. Final results should be used for standard novelizations.

2. Use of accumulation to support the energy system

   Stability of electric power supply is - as a term - closely related with electrical energy production gained from renewable power sources (mainly from wind and photovoltaic power plants). The research will be focused on possibilities of accumulation of electric energy produced from renewable power sources with the help of modern technologies while focusing on hydrogen (VRB systems) utilization, accumulators based on Lithium and pumped storage hydro plants for its accumulation. The result of the work will be the draft measures in the energy system, which can solve time disproportion between electrical energy supply and take-off from the renewable power sources. The solution is connected with computer simulation (Matlab) and experimental measuring on a real model. The condition for successful defense of this work is to complete at least one month long internship at a foreign university.
