[SOLVED] Designing Automatic Voltage Stabilizers

Status
Not open for further replies.
Re: Voltage Stabilizer using microcontrollers.

under over voltage setting is fix in hex file.
you don't need to set under over voltage setting according to that hex file.
 

Re: Voltage Stabilizer using microcontrollers.

Hi

I think you will find all the information if you study below all the post. Further we will help you more, when you described your details.

Thanks
 

Re: Voltage Stabilizer using microcontrollers.

How can I change the delay 5Min and 3Sec. Thanks Alotzzzz,

- - - Updated - - -

How can I change timmer to 5Min and 3Sec; Thankzzzzz
 

Re: Voltage Stabilizer using microcontrollers.

do you have static voltage regulator design (SVR) ??

Re: Designing Automatic Voltage Stabilizer

Mr. irfan ahmad
I liked the circuit developed by you using pic16f676
But why when Brutus tried to operate at low voltage stop all
relays????
I ask you to help me.
Thank you my friend
 

Re: Designing Automatic Voltage Stabilizer

sorry irfan.
proteus 8 professional.

look at this my friend
**broken link removed**
all relays Works at 2.3v

and look at this
**broken link removed**
all relays off Except 9 at 1.6v
 

Re: Designing Automatic Voltage Stabilizer

this software is basically PID controller.
software read output voltage and check if these are less or grater then set points .
after checking decide either on any relay or off.
*********************************************
for checking of this software you should require a variable transformer to change input voltage.
proteus does still not have variable AC voltage source or maybe i don't know about it .
if anybody can solve this matter then simulation will possible.
 

Re: Designing Automatic Voltage Stabilizer

Do you have mikro C code irfan Please

- - - Updated - - -

Thank you jayanth.devarayanadurga
 
Re: Designing Automatic Voltage Stabilizer

Can you post the Source code for the Circuit
 

Re: Designing Automatic Voltage Stabilizer

Add my voice to srenjis
Thanks for your help irfan
