Control circuits of eddy-current brake
Hofmann, Oldřich ; Knobloch, Jan (referee) ; Huták, Petr (advisor)
The thesis deals with the design of control circuits for the eddy-current brake, which will be used as main component of the dynamometer. The thesis focuses on the design of transistor inverter used for driving the eddy current brake and the design of speed regulation. The thesis also describes various types of brakes used in dynamometers and the overall concept of dynamometer electrical systems. An integral part of the thesis is also the test of the current controller and simulation of the control system at MATLAB – SIMULINK.

Laboratory machine-set with induction and DC machine
Hudák, Ondřej ; Feiler, Zdeněk (referee) ; Červinka, Dalibor (advisor)
The work addresses the design and implementation of a universal laboratory workstation designed to teach a course on electrical drives. Workplace will be formed sets consisting of DC motor with permanent magnet on a 400W power supply voltage of 24V and induction motor with 180W power on 3x24V. The engines are connected through a flexible shaft coupling. The asynchronous motor is located on the extended shaft resolver for scanning speed and rotor position. Both engines will be supplied from the transistor inverters. The workplace will be designed for maximum clearness and resistance to damage by improper handling.
