Single stage PFC fo constant voltage supply

Posted by: michael.finch@… on 05/21/2015

Hi,

I've searched the forums for advice on whether PI have yet developed a device for a single stage

power factor corrected low power constant voltage supply. No luck so far.

Plenty of material on PFC constant current LED drivers - but not CV.

Am I missing something?

Hi , Thanks for Posting your question into forum. What exactly your output power specifications? Our Hiper PFS product is power factor control IC. You can use the PFS IC for Power factor correction spec.

Hi,

I was looking recently solution for CV/CC with single stage PFC. I found two designs, which might be interesting for You:

http://ac-dc.power.com/design-support/reference-designs/design-examples/di-168/
http://ac-dc.power.com/design-support/reference-designs/design-examples/der-136/

Both examples are for LED power supplies, but in my opinion using only CV control is not a problem in this case.

Best regards,

Michal

Thanks a lot Michael for providing me Information, yes you can have CV control design.
