Flyback converter question

Practical limits are about 500W though 1kW would be possible. Much higher efficiency would be achieved using a forward converter. As a side interest I have a design for a single transistor Flyback that provides an excellent power factor. It does not require a special control IC o achieve high power factor. It does require an additional inductor.

Thanks for your reply, but why the Flyback converter is limited to 500W through 1KW, what is the reason of that ?

Hi,

It has to do with radiated noise/filtering of ripple. Above 500W you get more power from a forward converter per dollar than a Flyback. Yes you can parallel a number of Flybacks to do the same thing but less expensive to change to another technology. Dave
