Hi. Zener diode have a fixed voltage. such as 6.8v and other . if input side change voltage any problem then zener diode give fixed voltage in out put of this circuit . it full fill give 6.8 v . it do work same as a stabilizer.
IC is to do work a switch , amplifier ….

My need a Automatic DC 12 v Lead acid Battery charger circuit diagram. please help me.

Dear Frank ,
thanks for your tips, actually when i am 3rd year i select a topics . but now i think it is not perfect for submit 4rth year final project. my need a interesting and powerful project . your comment is good .
thanks by. ……..
