home.netvigator.com: Cuk converter Citat: "...The Cuk converter is a new SMPS topology at this moment. It include higher efficiency, low input and output current ripple, minimal RFI, small size and weight..."
boostbuck.com: Easy Design of the Boostbuck Family of Converters: Background Citat: "...The explanation for this shift in philosophy of design is generally ascribed to personal, professional, political, and financial forces. In truth, I believe that the reason is far simpler: In the two intervening years, nearly every engineer in the field made some attempt to design one or another of the Boostbuck topologies, but failed miserably!...Then I realized that most designers had gone through essentially the same sequence of design attempts. Namely, they had set out to build an Integrated Magnetics Cuk Converter..."
boostbuck.com: Easy Design of the Boostbuck Family of Converters: Beef Citat: "...Gus: I visited Dr. Cuk at his Irvine laboratories not long ago--he is an old mentor and friend of mine. He told me himself that the original patents on his converter had expired. His company has patents on further mods to the topology still in effect, but the original topology is no longer patented. It is this original that I deal with on my site...Gus: Nothing on my website is patented..."
boostbuck.com: Easy Design of the Boostbuck Family of Converters: The Four Boostbuck Topologies Citat: "...Coupled Inductor Cuk Converter...The procedure yields a control function with a single RHP zero, which cannot be damped out... [] ...Integrated Magnetics Cuk Converter...This fourth topology, which features zero current ripple at both input and output...It is not suitable for use in a power supply, since the control function contains two RHP zeros that cannot be damped out..."
