Thyristor Charger Project Page 4

Ok, I have updated the drawing, and the parts list...
You should be aware that the PCB is made after the ampermeter !

If you would like to make a thyristor charger for greater amps, you should just
take a bigger Thyristor U1, an a greater heat sink. I took a PC cooler, and put it
on secondary of a transformer trough gretz, 100uF/25V capacitor, and a LM7812

If you would like to receave a design files for Proteus ,you can contact me on Email
I will be glad to help you in any way...

Here you can see where to put the components:
A,K,G in the bottom are for Thyristor no1 witch is a 2N2324 or (BRX49 witch I used)
A,K,G in the midle are for Thyristor no2 witch is a large type KT708
mounted on a heat sink (+ PC cooler) with wires.
P1-1, P1-2 are for POTENTIOMETER no1
P2-1, P2-2, P2-3 for POTENTIOMETER no2
+14 is output from the secondary trough fuse and Ampermeter (if you need one)
-14IACU is common for the secondary and minus from battery
