DC-AC converter 12 V / 230 V for car applications
Jezerčák, Martin ; Šebesta, Jiří (referee) ; Brančík, Lubomír (advisor)
This work deals with a proposal for increasing DC/AC inverter for use in cars to power electronic devices on 230 V. This work is divided into two parts, theoretical and practical. It consists of three chapters. In the first chapter I developed a voltage converter, its breakdown, a breakdown by function, and the usage of individual connections. The proposal converter with the integrated circuit IR2153 is described in the second chapter. In the third chapter I processed readings and I visualized graphical dependencies of converter that was produced and purchased.

Inverter 12 V DC to 230 V AC with Protection
Navrátil, Petr ; Šilhavý, Pavel (referee) ; Kubánek, David (advisor)
This bachelor thesis deals with converter, which alters 12 V of direct input Voltage to 230 V of alternating Voltage output with frequency of 50 Hz. Introduction describes the basic parting of convertors. The chosen concept of designed convertor was based on that chapter. The practical part describes construction of this convertor including necessary safety shielding. At the end, the construction of the converter was tested by practical measuring and it was proven that the result meets with required values with slight anomaly.

Model of electric vehicle in SIMULINK/SIMSCAPE program
Kachlík, Jan ; Klíma, Bohumil (referee) ; Huzlík, Rostislav (advisor)
The topic of this diploma thesis is mathematical model of electric vehicle. The traction drive consists of Li-Ion battery, free-phase DC/AC converter and permanent magnet synchronous machine. The main goal of the thesis is development of function model and making simulations in SIMULINK/SIMSCAPE program. Work is divided into three main parts. The first part is dedicated to the theoretical description of the main drive components. The second part describes partial subsystems of the model. In the last part is build a complete model of electric vehicle and simulated different driving mode.

Three-phase converter for synchronous servomotors
Perout, Miroslav ; Folprecht, Martin (referee) ; Červinka, Dalibor (advisor)
This diploma thesis is dealing with the design of a DC / AC converter for the control of PMSM motors. In the first step, the type of motor and the possibilities of sensing the position of the rotor are described. Subsequently, the power section is designed and the losses, heating, and approximate efficiency of the inverter are calculated. In the following step, the processor is selected and individual communication and protection circuits are designed. At the same time, control algorithms are analyzed. The last part is describing the implementation of the PCB and the inverter as a whole.
