2. Three-phase bridge rectifier working at multiple commutation
3. Three-phase AC/AC converters, diagram of work at resistive load and at inductive load, backward influence
on the feeding network
4. Utilization of power semiconductor converters in non-drive applications, electrostatic separators, welding rectifiers,
battery chargers, superconductive magnetic energy reservoir, induction heating
5. Reactive power compensation, contactless switches for phase control and cycled control, softstarters
6. Resistor pulse control, cathodic and other types of prevention against electrochemical corrosion
7. Power transistor in switching mode, switch on and switch off processes, influence of the load type, limit values,
permissible operation area
8. Loss and lossless snubbers for switching off and snubber for switching on, realisation of the three-phase bridge
transistor voltage source inverter
9. Modern controlled drive, its components, function structure, control principles, pulse width modulation methods
10. Principle of vector control, basic structures, transformation of asynchronous machine equations to various
coordinate systems and used mathematical models
11. Principle of direct torque control, basic structures
12. Principle of pulse width modulated rectifiers, rectifiers with pulse width modulation of current type and with pulse
width modulation of voltage type
