Good day everyone. Pls can someone help me with a material or textbook that will give a detailed explanation of AC automatic voltage regulator design. Thanks.

 

Is this for a car alternator, or mains AC generator?

 

I have built a simple one using a LM311.
Or do you need to duplicate the current types, the one above was similar to the first electronic types that replaced the electromagnetic ones in automobiles.

@Dodgydave the mains Ac type. it should be an electronic design regulator.
@MaxHeadRoom Wat i need is the electronic type. Thanks

 

Dumken, you need to describe more about your application. Give us specifics. Your words so far are too general. If you don't have any specifics, you need to get them or you can't design something like this. Here are some questions for you to get specifics:

How do you intend to use this? What is the input and the output, AC/DC, voltage, frequency? What supplies the input, battery or mains or what? What does the output connect to?

 

If you're talking about going from a low-voltage DC input (like a car battery 12V) to mains-type AC voltage (220V 50Hz or 110V 60Hz) it's called a power inverter or just "inverter". Google "inverter design" and you'll find a lot of stuff.

 

Wat i need is the electronic type. Thanks

The LM311 electronic version is a simple circuit, the reason that it was replaced in automobiles is due to the the radio interference caused and inline suppressors were needed for the radio.
I have also used it to control the field for 240vdc generators also.

My guess is he needs a line voltage stabilizer like a constant voltage transformer.

Otherwise I associate the term automatic voltage regulator with generators.

 

Why it is actually called "automatic"?

 

on power ines, their called tap changers. an electromechanical switch to change taps on transformers. does it automatically too.

Aha, that makes for the "automatic" part. I supose that then, the regulator part will make the "steps" not evident.

 

the switch elements are make before break, usually submerged in oil. usually seen in a group of three that look like transformers on a pole.
