I looking for schematic of SCR regulated power supply, but I can't find
anything usefull. Can you help me?
Best regards!

j.b. miller said:SCR regulator is simple to build...
standard transformer and full wave bridge
bridge feeds anode of SCR
resistor from that point to gate ,with zener to ground.Zener sets output
voltage.
big capacitor from SCR cathode to ground.
I've used this 'bucket' regulator for over 30 years in various projects,
never had any fail,even in telecom applications.
Values obviosly depend on curent and voltage requirements.....
..but it is a start...
good luck

j.b. miller said:no......the zener only allows the SCR to turn on until the cathode voltage
equals the zener's value( -.6 v of course).
and this circuit as simple as it is has worked for over 30 years, 24 7 as
the saying goes.....
