Hello to all... is there anybody who has already implemented a digital power factor controller and can enlighten me on this topic? (Maths and more). For a redesign I want to replace the analog pfc- chip. Thank you in advance Thomas -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
