I am trying to design a firing controller board for industrial scr. but i do not know which type of scr will be connected to it. so i have problem with choosing pulse transformers. how can i choose transformers that work with all types of welding scr???

 

Many more details are needed, Application? Load? What type of welding?
Supply details??

 

hello dear max.
thanks for your answer, my board is supposed to control semikron welding scr used in spot welders. the scr is used to control the input voltage of the welding transformer. the welding transformers are around 200 to 300 KVA.
and the input voltage can be both 220VAC or 400VAC.
