Usage of High Power Inverters in High Voltage Sources
Zemánek, Miroslav ; Janča, Jan (referee) ; Boušek, Jaroslav (referee) ; Patočka, Miroslav (advisor)
This work is concerned with power inverters for alternate high voltage power sources. The theoretical part describes the topology of inverters that can be used in alternate power sources. A model of voltage transformer is described in details to better understand the parasitic effects that are inevitably present in high voltage power sources and, therefore, have to be taken into consideration at the design of high voltage power sources. The work is oriented to problems of alternate high voltage power sources for ozone generators. This is the reason, why the theoretical and, partially, also the experimental part deal with the properties of ozone and its use. The experimental part solves high voltage inverter with capacitive load that is formed by discharge element of an ozone generator. Designed inverter is able to feed the capacitive load with high voltage at very short periods of time from several microseconds up to tens of nanoseconds. In comparison with the length of voltage pulses in common ozone generators, this pulses are more than 100-time shorter. This has a positive effect to silent discharge characteristics.

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.

230 V inverter for isolated mains supplied from solar cells
Michálek, Pavel ; Procházka, Petr (referee) ; Martiš, Jan (advisor)
In this thesis is presented detail design of power part of DC/DC converter and output inverter. This device will serve for creating an artificial network in a family house where it will be used for supplying selected household appliances which are designed for use in AC network. The converter will be supplied with DC voltage. This tension will be obtained from a system of photovoltaic panels. The output voltage will have alternate character and it will be close to the network voltage 230 V/50 Hz. In the introductory part of thesis are discussed possible topologies of converters and output inverters. Subsequently are designed individual parts of supply inverter. In the final part there are shown waveforms of important values and is given a thesis evaluation.
