Anotation:
At first a physical description of basic properties and basic types of materials for electrical engineering is carried out. Types of conductors, superconductors, insulators, magnetic materials and semiconductors, which are used in power electrical engineering, are presented. The stress is put on relationships between properties, technology and the use. The student will meet, in higher detail, with ceramics for electrical engineering, with properties of mica, glass and their applications, with environmental conductive joining, with materials for thin and thick films and with selected nanomaterials and their applications.
Study targets:
The aim is to identify the structure and properties of basic materials used in electrical power and to become familiar with the measurement of these properties. Acquired knowledge is essential for the subsequent courses of technological nature.
Content:
The course deals with how today standard materials suitable for the manufacture of devices for power electronics, so materials completely modern. The first group includes in particular, conductors, semiconductors, superconductors, insulators, dielectrics, and magnetic materials. From the second group, it is possible to designate the nanomaterials and smart materials. They are not only presented information on basic types of materials and their properties, but also information on selected applications of these materials.
