how Ichose ferrite core

[Alian]

Hi for all Iwant to ask and help how Ichose suitable of ferrite core for any application that Iwant to make it (example) etd ec ee and ei cores And how much power (watt) that we can get from ETD49/25/16 and EC49/27/17 on 100Khz frequency and what is the different between EC and ETD cores because iwant to make inverter welder mashine and Ihave the two cores that Itold of them from china tv please any one help me and thanks for all

Thank you mr peter ETD49 suitable for welder mashine 15volt 80ampere output and 220v AC input and how many numer of turns for primary and secondary on 80Khz

 

[tpetar]

For welder device you should use copper strip specially for secundar.

See this project:

thankyou very very very much mr peter and I want to answer me how much power that I can get from ETD49/25/16on80Khz because I want to make mini welder 70-80 ampere and Ican not to found the core in the circuit that you put it

 

[tpetar]

Switching transformer Tr1 is wound on two ferrite EE cores, each with a central column section 16x20mm. The total cross section is therefore 16x40mm, the core must have no air gap. 20 turns primary winding is wound using 14 wires of a 0.5 mm diamater. It would be better to use 20 wires, but they didn't fit to my core. Secondary winding has 6 turns of copper strip 36x0.5mm.

what about ETD49/25/16 Iwant to use it how much power

How can you possibly expect to make a SMPS welder with zero knowledge about SMPS. I see smoke in your future.

Hi mr Flapjack Iput my questions because I want to learn and to know because If Iknow Idon't put my qustions and you have to be careful when you want to put your reply!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! thanks

Thanks mr tpeter for your information and your help

Alian, if you want to learn then start with a LOW power SMPS. You are going to burn up a lot of components and this will cost a lot of money if they are high power mosfet's.

hello peter u given very good data of welding machine is it commercialy succesfull?
