Basic classification of power converters: AC/DC, AC/AC, DC/DC, DC/AC. Cascade of few converters. DC-bus. Static thermal phenomena. Cooling of semiconductors. Demanded thermal resistance of the heat sink. Active power; its calculation in special cases. EMC in LF region. Power factor, total harmonic distortion factor. Power switching devices, overview: diode, thyristor, triac, BJT, MOS-FET, IGBT, GTO.Special chapters from the semiconductor theory. Chip structure of these power devices: fast diode, slow diode, symmetric thyristor, asymmetric thyristor, bipolar transistor, MOS-FET, IGBT, GTO. Detail analyse of the switch-on, and switch-off processes in the transistors. Switching loss calculation.Rectifiers: non-controlled, controlled. Typical loads. Mean value of output voltage. Net rectifiers for supplying of transistor converters. AC/AC converters: 1-phase, 3-phase. Loads of R, L, R-L, R-L-Ui types. Phase control of triacs. DC/DC transistor converters. DC/AC transistor converters (1-phase, 3-phase). Control strategy of DC/DC, and DC/AC converters. PWM, sinusoidal PWM. Magnetic phenomena in the power electronics. Transformer theory. Mathematic models of the voltage transformer and current transformer. Switch-mode supplies. DC/DC converters with the pulse transformer. Single-end, and double-end buck converters.
