[SOLVED] SMPS Power Inverter with TL494,1404

The configuration is equally good in terms of duty cycle. 4013 outputs are 50:50 duty cycle.
 


my friend,
in a pwm IC like SG3525 or TL494 has so many other functions like error correction current sense shutdown and even the most important of all dead time delay, so comparing a pwm chip with 556 and4013 put together could not make everything possible
 

Sir I need a detailed stuff regarding 1500W inverter based on smps. Please Sir upload all the stuff as well as circuit diagram. Thanks
 


Your statement is correct.
Can you mention other chips like SG3525 and TL494.
 

1500 Watt Inverter using TL494, LM324, CD4013B, NE556.
you can use 75N75 on DC side and IRF740 on Output side. Use IE40H ferrite core with 3+3 turns on Primary side and 63 turns on secondary side.

thanks "KG300" but as usual you only like to give little bits and pieces of information !!where is the circuit diagram/schematic?

Thank you kg300,can you upload the pcb in its software standard .instead of pdf file.

what are the size of the copper wire for both primary and secondary winding etc .
 

thanks kg300 for posting such a useful things.but I've one problem.you have used ei core transformer.it's not available in our country.can I use ee core transformer istead of ei core?
 

thank you very much...you have solved my problem.....now i'm making pcb...hope It will be alright.......

but what the differnence between ee and ei core transformer,,,instead of shape?
 

This is called Litz wite. A Litz wire consists of multiple fine strands of insulated solid wire twisted together to form a single conducting bundle.
More simple words, take 4 wire of AWG#24 (enameled wire) and wind them together (to reduce the skin effect and increase the total wire gauge.)
 

Thanks for the answer. I understand.

There is any specific way to wind them all together? I mean, they have to be aligned side by side, they can be curled and then wind, etc?
 

what will happen if we wind the complete primary first and then complete secondary?
