ud1208

Need help with DC/AC inverter from:
h**p://www.eserviceinfo.com/downloadsm/13181/_UPS_PIC16F84.html.

Cant find replacment or datasheet for UD1208, and there is no info on the schematic about transformer T1 and T2 ( U prim., U sec. and P)
 

inverter 12v 220v

I too didn't find the data sheet of UD1208 . But don't worry you can use any op amp

like 741 as a pin to pin replacement . It is used as a comparator. T1 is a charger +

mains a.c sensing transformer sens winding is 10 to 12v. Charging winding should be

24 to 30 v C.T . 2 to 4A. T2 is 10 + 10V at 50A,(for 500W) sec could be 230V,2.21 A.

Other winding is for out put regulation and it is 10 to 12V
 
ud-1208 charger

ud1208-precizion OP of soviet union, serch datasheet by К140УД1208

can we use FET,s instead of power transistors with this circuite ?
 

yess asif power mosfest can be used in the palce of transistor
 

Thanks It might help me also.
@Asif Hameed & Malik
Can you show me how can you power transistors with MOSFET. Sorry but I am at very beginner level

One more thing
I can not find what is the rating of this circuit 1KVA or what?
 

\tan \prod_{n = 0}^\infty talibsyed

Did u Try this Circuit or not!
the charging transformer should be 15+15V
For MOSFETs a driver circuit may added. to drive MOSFETs \prod_{n = 0}^\infty
 

the transistors and diodes are russian-electronic parts. i can't find the replacement for a western component.please help
 

dear don't afraid of experimenting new things
the op amps are used as comparators you can
also use 741 or quad op amp ic lm324 kt series
can be changed to 2n or 2sb 2sc (japan).
Give it a try.

hi
friends i think your idea not bed for 741 and 324 any one use there want simle comprator use any one 339 /393 358/324 1458 bla bla hahah
 

can i make ups without using any additional ic with the help of pic16819 only having fixed volt output (PWM) 50 Hz and low battery cut and cut the battery when at full ? but only using a single PIC16f819 and no any dditional IC?
 

you can use LM358 instead.
Actually it is not an inverter circuit but a UPS
