Hello everyone, I am working on a project in which I need to make a broadband/pulse transformer. The transformer will operate in the 20-80kHz range. The transformer will use about 20 watts of power. I need a turns ratio of 1:3. 20V input 60V output It's just for hobby use. I don't have the money to pay an engineer to design it and it does not have to be perfect, I just need to get a good square wave on the secondary side. I have tried to make this type of transformer in the past but I find it very difficult to get a good square wave on the secondary side. I usually end up getting AC on the secondary side. I know this could be due to a number of factors such as coil capacitance, core material, or leakage inductance. So, my question is, how difficult is it to make a broadband/pulse transformer when one only has basic electronics knowledge? What general rules should I go by? Could anyone here offer any suggestions or advise...Is it even worth my time to try to figure out?
