Description and contextualization of the subject

Based on the recently released forecasts, the electric energy consumption worldwide will increase by almost 56% until 2040. Almost half of the electricity demand will be generated by renewables, whereas the conventional energy sources (fossil fuels) must be utilized by causing the lowest possible energy losses enabling higher energy efficiencies. Power Electronics will play a key-role in the development of the future electric energy systems. The task of Power Electronics is to process and control the flow of electric energy by supplying voltages and currents in a form that are optimally suited for user loads. The development of state-of-the-art low and high power semiconductor devices, make Power Electronics to hold a leading role in dc/dc, dc/ac and ac/dc electric energy conversion for a wide range of application areas. Such areas are electricity transmission and distribution, renewable energy integration, transportation, household appliances, medium and large-scale industrial equipment, aerospace electronics, medical equipment etc. Individual challenges can be found for each specific application area. However, the biggest challenges in Power Electronics are associated with achieving higher energy efficiencies, higher power densities, higher degree of reliability, immunity against electromagnetic interference (EMI), control stability and robustness etc. In order to deal with the individual challenges, the basis of Power Electronics must be first studied in details. This course focuses on presenting the fundamental Power Electronics Converters concepts along with basics of controlling these systems. The most common applications of Power Electronics are also treated.
