Fast-charger for lead-acid batteries 12 V
Kopuletý, Ondřej ; Pazdera, Ivo (referee) ; Vorel, Pavel (advisor)
This Master thesis deals with modification of lead battery charger connection. In particular, changes are made to the control board. The theoretical part describes the principle of charging lead batteries and the description of the basic types of switching power supplies. Furthermore, the dimensioning of important components in the circuit together with the optimization of the switching frequency and the parameters of the high-frequency transformer are also presented. At the end of the thesis is the procedure of assembling the whole charger.

Charger for lead-acid batteries
Kopuletý, Ondřej ; Procházka, Petr (referee) ; Ondrejček, Vladimír (advisor)
This bachelor‘s thesis deals with the modification, construction and testing of lead-acid battery chargers. It is described the principle of charging the batteries and individual topology of the switching power supplies. The original schematic diagram is taken from the thesis of Josef Kadlec. Diagrams of a power and control circuit have been modified. The topology of the charger is two switch forward converter with pulse transformer. The charging method is constant voltage with current limiting.
