100amp 12 volt ps battery charger

My new battery charger, quick charge up to 100 amps, slow charging around 2 amps. I had extra parts so I Incorporated a 5 volt charger in the PS so I can use at my bench when not using for a car battery. The values in the drawing's are not exactly the same as real world, but you get the idea of what to do.
I'm using 2n3055 for the power control capable of 15 amps each @ 10 = 150 amp.
I have a separate power supply for the 12 control voltage and the same for the 5 volt control.
No worries if the main transformer drawing down in voltage

How are you lucan, i had a bit of surgery, took some time off. The transformer i used was made just for this by a fellow i know who run's a transformer repair shop.

I suggest that you find a old welding machine, too repurposed transformer. Welder make around 28 volts and is a large variable current transformer (Variac) most can produce 100 amps to 250 amps, plenty for making lots of things smoke.
