PIC16F876A Based A.V.R ( VOLTAGE STABILIZER )

I have be thinking about a pic microcontroler based voltage regulator for about 3 years now; last week i install a 2.5kva 36V inverter for a consumer of mine... 3 days later he called me that the inverter is not charging the battery well... so i ask him to call me and check the input voltage on the lcd screen when ever their is a mains supply (NEPA).... so he called  confirming that the input voltage was 108volt; we had to design a  2kva automatic voltage regulator from 80V - 260V...

Features:
Low voltage protection
High voltage protection
Delay function
Calibration mode
Delay indicator
High/low voltage indicator



4 Relays voltage stabilizer

 
 ON 187V INPUT TEST ON PROTEUS

 ON 218V INPUT TEST ON PROTEUS 

 
 ON 262V INPUT TEST ON PROTEUS WITH HIGH VOLT GUIDE 



 
RELAY CONFIGURATION

 
TRANSFORMER CONFIGURATION



 
A

 
B

 


 



  








Repair of 2kva AVR


Old board


New board

    Hi,
    Thats a nice solution to the voltage problem with the UPS :)

    Also the UPS and AVR can be combined in one machine.
    Do you have a combined UPS and AVR design?
    Regards,

    Hi everyone, I saw comments from people who had already got their loan from Anderson Loan Finance. Honestly, I thought it was a scam, and then I decided to make a request based on their recommendations. A few days ago, I confirmed in my personal bank account amounting to $15,000 dollars which I applied for. This is really a good news and I am so very happy that I advise all those who need a real loan and who are sure to reimburse to apply through their email (text or call) +1 719 629 0982. There are sincere loan lenders! They are capable to lend you a loan. Contact Mr Anderson E-mail: andersonraymondloanfinance@gmail.com
