Preparation for function demonstration of basic types of oscillators
Venhoda, Jaroslav ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
Bachelor's thesis deals with basic types of oscillators. Oscillators were divided into groups in the introduction. For the practical implementation was chosen four different types of oscillators. For each type of selected oscillator was done circuit design. Subsequently, the design was simulated by PC software OrCAD PSpice. The proposal includes a possibility of the control device by switching between outputs and tuning oscillator's frequency.

Single-phase DC/AC converter with output parameters 230 V / 50 Hz / 100 VA
Smolák, Martin ; Martiš, Jan (referee) ; Vorel, Pavel (advisor)
This master‘s thesis focuses on optimization of power and control circuits of an inverter, which was developed at UVEE. The principle of function and circuit implementation of a single-phase inventer, various calculations (design of an LC filter, DC link capacitor, semiconductor elements and heat sink) are described in the thesis. A design of fast overcurrent protections, oscillator and saw signal generator is included. Furthermore, a printed circuit board was designed which was optimized by thermal simulation in the Workbench Ansys. Subsequently, the printed circuit board was mounted, debugged and verification measurements were performed on it. At the end of the thesis there is a documentation for the implemented equipment.
