Microprocessor controlled BLDC motor inverter realization
Mikuška, Martin ; Cipín, Radoslav (referee) ; Knobloch, Jan (advisor)
This bachelor’s thesis goes into electronic commutated motors, their inverters and specific parts of the general pulse converter. Next it is described step-down converters, push-pull converters and the principles that are supported by practical exercises. The next part describes the design of the power transistors driver and problems of galvanic separation by optocouplers.

Electric drive for motorcycles
Černošek, Martin ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The diploma thesis is focused on rebuilding of the combustion engine powered motorcycle to the electromotor powered motorcycle. In the thesis is chosen the suitable electromotor, next is designed the accumulator system, then is created the construction design of location electric system in the motorcycle frame and at the end is made the strength analysis of the mechanical parts. For the construction design is created 3D model in SolidWorks. The diploma thesis is also focused on comparison the motorcycle powered by combustion engine and the motorcycle powered by electromotor in the Supermoto race.

Modelling of linear power drive with DC motor for control purposes
Vrbka, Michal ; Březina, Lukáš (referee) ; Houška, Pavel (advisor)
In my diploma thesis, I developed the model of a linear actuator for the control purposes. The first part summarizes the literature research of currently available linear actuator systems. The work further describes some of the capabilities of the simulation environment Matlab which was used for the creation of the computer model of linear actuators. In the last part, this theoretical model is compared with already available physical model of the system.

Iverter for three-phase motor
Mikuška, Martin ; Červinka, Dalibor (referee) ; Knobloch, Jan (advisor)
This master’s thesis goes into design of particular circuits for three phase inverter. Inverter’s control is ensured by digital signal controller MC56F8013 with his program. Principle of control is suggested for individual motors. Inverter design considerate universal use and capability for any three phase motor. Particular blocks are compatible each other.

Positioner for Solar Panel with Power Efficiency Optimizing
Kreysa, Karel ; Punčochář, Josef (referee) ; Šebesta, Jiří (advisor)
This thesis is focused on design and prototyping of solar panel position control system for an obtaining of the maxima renewable energy from sun. In this thesis, various ways of solar panel positioning are considered and analyzed. Consequently, a construction arrangement of the positioner is presented. It is mechanically adapted to obtain the maximum efficiency in typical environment corresponding with the Central European geographical latitude. Different methods of sun monitoring are considered and analyzed. On the basis of this analysis, a proper prototype of sun monitor for exact positioning with disturbance filtering has been constructed. Following part of work is devoted to stable, fully automated, control subsystem for reliable functionality of solar system. A suitable microprocessor with a robust firmware has been implemented to this control unit. Finally, system parameters measurement and closing analysis of gained renewable energy and backflow computation is presented in the end of this diploma thesis.

Mobile Wood Splitter
Felcman, Miroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main aim of the bachelor thesis is to design a mobile horizontal woodlogs splitter according to preset parameters. The part before the main design of a splitter is focused on different types of mobile splitters with the subsequent focus on the individual structural design of horizontal splitters. The next part is dedicated to design and calculation of a hydraulic circuit of the splitter that generates the required cutting force. There is a calculation of final splitting force and other working properties for all individual components of hydraulic circuit. The individual components of the splitter are stressed by the splitting force. There is a strength check of exposed parts in the last part of the thesis. The work also includes drawings of selected parts.
