Dear all, I am a bit confused regarding power output of ferrite core transformers. According to data sheets and comparison what everyone else did by reading forums over here it was found that though data sheets (TDK Epcos cores) say for example an ETD 49 can give around 700 watts at 100Khz in a forward converter mode. Thus Microsim and also Ludo got around a kilowatt and more using half bridge topology. From what I noticed the core area and also the frequency play an important part in this factor. Can anyone tell me why and how is this achieved?
I already build an smps with an EI 40 core from an old atx psu but only got a marginal 300 watts till now. I build it from scratch and also took a few ideas from previous articles found here
Here is my work so far::SD
