Car-battery charger
Kadlec, Josef ; Procházka, Petr (referee) ; Červinka, Dalibor (advisor)
This bachelor’s thesis is considered by projection and construction of the car battery charger with switching source. One-pulsed conducting changer is base of this charger. The charger is intended for accumulators of nominate voltage 6 and 12V. Accumulators are charged by method of constant voltage with current limitation of 0.5A, 5A, 20A and 50A. Value 50A has reason during stating of car for example in winter, because the charger helps to battery. The device is equipped with additional protection, which protects the charger and also the accumulator and the supply network. Three pilot lights are the next equipment of the device.

The inverter based battery charger
Kadlec, Josef ; Pazdera, Ivo (referee) ; Červinka, Dalibor (advisor)
The aim of this master’s thesis is provide detailed information about car battery’s charger with a switching power supply. The kind of this power supply is one-pulsed conducting inverter with transformer. The charger’s rates of nominal voltage are 6 and 12 V. The method of charging is charging by constantly voltage with a current limitation. The values of a current limitations are 0.5A, 5A and 20A. The charger’s maximal current is 50A. This current can help to the accumulator with starting of a vehicle. This device is equipped by indicators which indicate the end of charging.
