9. Course Prerequisites Passed: Fundamentals of electric circuits
10. Course Goals (acquired competencies): The objective of this course is to give to the student fundamental knowledge about power converters, and how they work. Students will be also introduced with their application and techniques of computer modelling in order to study their performance and characteristics. With this course students will be competent to determine the characteristics of power converters and perform full analysis of them, as well as be able to model and simulate their performance.
11. Course Syllabus: Introduction and classification of power converters. Characteristics of semiconductor devices applied in power converters. Single phase uncontrolled rectifiers. Single phase full-controlled rectifiers. Three phase uncontrolled rectifiers. Three phase full-controlled rectifiers. Application of rectifiers for DC motor control and in systems with renewable energy sources. Complex topologies of rectifiers. Application of complex topologies rectifiers for high voltage DC power transmission. Commutation of current in rectifiers. Power factor and efficiency in rectifiers. Inverters. Output characteristics of single phase and three phase rectifiers. Single and three phase line commutated inverters. Single and three phase autonomous inverters. Application of inverters for AC motors control and in systems with renewable energy sources. Reversible power converters. Frequency converters. AC voltage converters. DC converters (choppers). Reversible DC converters and their application for DC motor control.
12. Learning methods: Interactive lectures, numerical and laboratory exercises, homework exercises, and study in electronic environment.
