I am trying to find transformer secondary minimum voltage. Is there any voltage drop across the pass transistors?
As I explained in the beginning of the page:
I would not recommend a secondary voltage of more than 18 volts. This is because the higher the secondary voltage is the more the pass transistors will have to drop to provide the 13.8 volts needed at the output. When high current is drawn a lot more heat will have to be dissipated by each transistor if the secondary voltage is high.
