Three-phase variable autotransformer actuator
Nevřela, Tomáš ; Červinka, Dalibor (referee) ; Knobloch, Jan (advisor)
The aim of this work is to implement an actuator for three-phase variable autotransformer. The project includes a theoretical base of electric actuators on the basis of which is chosen the type of motor, its method of control and regulator, necessary for a specific actuator. Parts of the thesis are design and production of hardware with microprocessor, consisting of control, measurement and power part.

Power outage simulator
Sýkora, Dušan ; Lieskovan, Tomáš (referee) ; Kohout, David (advisor)
This thesis is concerned with building a smart gadget that is able to simulate blackouts. This simulator is able to interrupt or limit supply of 230 V electricity from a power grid to the tested appliance for adjustable duration and with adjustable frequency. The gadget is controllable remotely via a web interface. For that purpose, components have been selected and a program written for a microcontroller. Finally, functionality has been verified on multiple appliances.
