1. Rectifiers with external commutation, controlled and semi-controlled in bridge and node connection, multi-quadrant connections. Influence of rectifier pulse and control influence on DC voltage waveform and current consumption from mains. 2. Pulse converters, control of pulse converters (version with constant current ripple and constant switching frequency), voltage quantity, multi-quadrant connections (2kv. ,4kv.). 3. Voltage inverters, single-phase, three-phase in PWM modulation. Switching states, voltage and current waveforms in different operating modes (for different loads including generator mode). 4. Frequency converters with voltage inverter, voltage and current conditions in the DC link for different operating modes (mains recovery), capacitor pre-charging, interaction with the power net. 5. Frequency converter with current inverter. Direct frequency converters (cycloconverters, matrix converters). 6. Voltage converters. Special power converters, high voltage converters (basic topology and industrial use). 7. DC drive topology (from AC and DC power supply). Block diagram for controller design. 8. Design of controller parameters for DC drive control. 9. Drive with asynchronous motor - scalar control (variant without speed and with speed sensor). 10. Drive with asynchronous motor - vector control, direct torque control. 11. Drive with synchronous machine powered from the network (reactive power control) and powered by frequency converter (speed control). 12. Drives with switched and synchronous reluctance motors, linear motors - basic principle of operation. 13. Design of electric drive type size - thermal and torque criteria for motor, design of semiconductor converter parameters.
