DC/AC one-phase inverter 230 V / 50 Hz / 60 VA for a back-up supply source with a galvanic separation
 Šoupal, Ondřej ; Procházka, Petr (referee) ; Vorel, Pavel (advisor)
The aim of this thesis is to design power circuits and control circuits of single phase DC/AC inverter and its practical realization. This work describes basic principle of single phase inverter. Next step is a solution of output LC filter, input capacitor and semiconductor devices. It contains block diagram of control circuits and it focuses on design of oscillator for pulse width modulation and current limiting. The thesis gives details about practical realisation and testing measurements. Technical documentation was prepared for this inverter.

Adjustable Laboratory Power Supply
 Skryja, Petr ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
The aim of this work is to enlighten the reader with topic of linear power sources and guide him through designing his own adjustable laboratory power supply. Design of adjustable laboratory power supply uses the stabilizer L200 with voltage regulation and current limitation. Device is expanded with digital part (using ATmega8 MCU) to enable peripherals control and measured values processing. The laboratory power supply will be constructed and its parameters will be measured.
