Course Handout Power Electronics

Abstract

Power electronics is a fundamental discipline of electrical engineering concerned with the static conversion of electrical energy using semiconductor components operating in switching mode. It enables the efficient adaptation of the voltage, current, frequency, or waveform of a power source to the requirements of a load or system. The main conversion structures include rectifiers (ACDC), inverters (DC-AC), choppers (DC-DC), and matrix converters (AC-AC). Power electronics relies on a close interaction between three fields: electrical engineering, electronics, and automation. Thanks to its performance in terms of energy efficiency, compactness, and flexibility, it is now ubiquitous in industrial systems, smart grids, electric transportation, renewable energy installations, and household appliances. Its ongoing development is also driven by advances in semiconductor materials and advanced control techniques, thus actively contributing to the challenges of energy transition and energy efficiency. This handout is intended for fourth-year engineering students in electrical engineering, automation, and electronics, and follows the official curriculum outlined by the Ministry of Higher Education and Scientific Research.
