automatic voltage regulator

[[email protected]]

i am currently doing project on Generator voltage control system.
Could you send me circuit diagram for automatic voltage regulator that
will give output voltage of 220V/50hz AC.

Sure!

You have a lot to learn, and not just about electronics. Like how to
communicate.
Care to give it another try?
We're here to help.

Not bad...

How about this:

.-------------------------------.

| |
| | output

Input o---------o MAGIC o-----------o

He may need the isolated version:


.-------------. .---------------.
| | | |
| | | | output
| SOME | | MORE |
Input o---------o MAGIC | | MAGIC o-----------o
| | | |
o---------o | | o-----------o

If you take the knob off a variac, you can fit it with a pulley. A
small gear motor can then turn the variac up and down. A meter-relay
and a power relay can then control the power to the motor.

Generator? You're using a DC generator instead of an
alternator? If it isn't a permanent magnet type, you'd
just trim the output voltage by modulating the field coil current.

To make it AC, there's lots of designs out there: look into
into "variable frequency controls" that drive AC motors,
for examples, or "power inverter" like provide AC in
automobiles if your needs are low-power.

I am so BUSTED!
