Thank you for the quick answer. I must be sleepy or drunk, when i look to the datasheet. Yeah, 45kHz makes much more sense.
I have analysed some Mosfet`s on Switching losses versus Rds losses for Push pull converter, see here
From the point of efficiency, those fast mosfet like the...
Hi DeepOne,
thanks for sharing your schematic and scope pics. Your schematic in the post #4 (TL494, push-pull) got my attention. Do i guess right, that the switching frequency is around 250kHz (2n2 and 5k1)? That would be quite impressive.
From the picture, your toroid transformer looks huge...
