Hiper PFS range for small PFC 100-265VAC, 400W

Posted by: treez on 03/28/2023

Hi,

I have offered to do a HiperPFS PFC for a company at 400W, 100-265VAC. (followed by an LLC) 37Vout.

Its for a consumer beauty product

But they believe a totem pole PFC stage will be a smaller and more efficient solution.

They want a really small solution as the customer may have to carry it on holiday etc.

Would you agree?

Hi.

Thank you for showing interest in Power Integrations' products.
HiperPFS-5 can only deliver up to 240W of continuous power at 90VAC.
It will not be sufficient for your power requirement of 400W.

Please refer to the HiperPFS-5 datasheet for more information.

Thanks, regarding PFC at 400W...do you believe that Totem pole PFC is more efficient then hiperPFS?.. or does the totem pole controller micro have a few watts of bias power, and so its not worth doing totem pole at 200-400W?

A comparison between HiperPFS-5 with a totem pole solution at 200-400W can not be made.
HiperPFS-5 can only deliver 240W of continuous power which is essentially the minimum power you are referring to.
Power Integrations does not have a totem pole solution that can be compared with HiperPFS-4 at 240W either.
Thank you.
