The course deals with power electronic converters and their elements. The most important objects of the course are: general definitions and mathematical tools of power electronics, one-cycle and multi-cycle DC/DC converters, diode and thyristor rectifiers, autonomous inverters and some specific converters..
The course is concentrated on calculation of parameters of the power converters, choice of their passive elements and semiconductor switches, as well as on the cooling and protection of these switches. The course includes special lectures devoted to development of the power converter utilizing the corresponding modern integrated circuits. The practical part of the course includes numerically solved exercises, exercises of simulation of the power converters, laboratory exercises. The most active students are provided with opportunity to design, build and test one of the studied power converters utilizing one of the available integrated circuits..
Goals and objectives
of the course in terms
of competences and skills
|The aim of the course is to teach the students to identify power electronic converters, describe their operation, choose a converter for a particular application and calculate its parameters, choose passive components and semiconductor switches as well as their protection and cooling elements for the converter. Another aim of the course is to develop practical skills of the students to build the studied converters (of ready to use power blocks), measure their parameters and test their operation.|
