Intelligent charger for lead-acid accumulators 12V/130A with an option "start-car"
Láznička, Martin ; Červinka, Dalibor (referee) ; Vorel, Pavel (advisor)
This bachelor's thesis is considered on a basic description of car battery charger with a support function “start-car”. A switching power supply creates a base of the equipment-this is why the charger is compact and easily portable. It is designed for 6V and 12V batteries. A charging by a constant voltage with a current limitation (to 0.5A, 5A or 20A) is used. The charger maximal current is 120A for a short-term load, so a proposal of an appropriate thermal protection is included in the project.
Electrical machine thermal protection
Němec, Martin ; Huzlík, Rostislav (referee) ; Mikulčík, Aleš (advisor)
This bachelor´s thesis deals with proposal for thermal protection of single-phase motor. The single part of thesis is devoted to collocation of motor temperature. Knowing this issue is important for thermistor right location. The parameters measuring and the model of simulated scheme are described in following parts. The simulated scheme is created in the Matlab programme, in a programme´s superstructure Simulink. At the close of this thesis, there are values measured and simulated compared.
Laboratory stand with motors and inverters
Ondrejček, Vladimír ; Vorel, Pavel (referee) ; Červinka, Dalibor (advisor)
This thesis proposes driver, which will be used in laboratory stand. The first part contains the typical characteristics, application and function of drivers. The second part deals with drivers, right selection of components, circuit diagram and printed circuit board design. Then the driver is realized and made operational tests.
Návrh rodinného domu a tepelná ochrana budovy
Hofman, Jakub
The bachelor thesis deals with the design of a wooden building with regard to thermal protection of structures. It is a family house with two floors of which the second floor is designed as an attic. The structures are designed to comply with the ČSN 73 0540 standard. The layout of the house is designed so that the living rooms are shaded in the summer, and so that there is a high degree of sunshine and heat gain from the sun in the winter. The theoretical part describes the types and properties of thermal insulating materials used in frame systems of timber construction. Thermal insulation is categorized into synthetic, mineral, organic and special thermal insulation materials. The materials are compared according to individual thermal properties.
