Hi all
I've a question about high gain power converter. i'm just curious about this.
Simply, we use boost converter for step-up, however when gain need to be larger, (about 30~40x )
we should consider coupled inductor boost converter (aka tapped inductor boost converter) for obtaining high gain.
Now I have a question.
How about using flyback instead of coupled-inductor boost converter?
First, MOSFET voltage stress (peak) at drain would be higher by VIN voltage.
Second, gain would be a little bit smaller than coupled inductor boost converter, but it can boost 30~40x with proper turn ratio.
I think the drawback of using flyback for high gain is above two factor. do you have any idea of another drawback with using flyback?
Thanks in advance.
