Electronic parts of small fotovoltaic power plant
Benda, Dušan ; Šťastný, Ladislav (referee) ; Bradáč, Zdeněk (advisor)
The thesis describes the design, implementation and subsequent testing of electronic circuits for usage in small photovoltaic power plants. It focused on the sub-power appliances, battery charging and monitoring of photovoltaic panels. Introduction of this work deals with selecting appropriate controllers for each subsystem and comparison of the proposed facilities with commercially available applications. A substantial part of the work describes the selected controller for each subsystem implemented and circuit design of the individual components of electronic systems in detail. For each subsystem are implemented measuring and comparing the results achieved.

Design of unit for Power HIL simulation of DC motor
Chalupa, Jan ; Maršík, Jiří (referee) ; Grepl, Robert (advisor)
This thesis deals with analysis and implementation of Power-HIL system that is designed to simulate real DC motor with comutator and permanent magnets. For problem analysis were used simulations of real components in Matlab / Simulink. The electronic parts of system were simulated with using the SimElectronic library. Idividual hardware components were designed according to simulation results. The outcome of this thesis is a power electronic simulator of real DC motor, which is implemented on dSPACE platform. The system allows software to setup parameters and behavior of simulated motor. The final system can be used for testing DC motor ECU (electronic control units).
