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.
