ABSTRACT
This project which consists of four chapters deals extensively with the design and construction of a battery charger which is capable charging a 12 volts, battery.
The first chapter which is the introductory chapter goes a long way in defining the battery charger and explaining of the mode of operation.
The second chapter went further to explain each component part of the battery charger. This ranges from:-
1. The transformer
2. The rectifier circuit
3. The filtering stage
4. Voltage regulation
5. Comparator
6. Thyristor
7. Resistor
8. Diode
9. Relay
10. Zener diode and
11. Light emitting diode (LED)
The third chapter explains more about the Testing Sensing and switching processes in the charger. It also gave the list of components and the circuit diagram of the battery charger.
The concluding chapter being fourth, tells us more about the circuit arrangements and the construction of casing and finally the overall cost analysis.
