Cuk-buck2 vs buck converter SHOOTOUT-Dr. Cuk presented at the Typhoon-HIL exhibit at APEC 2016

Publicado em 7 de abr de 2016 Dr. Cuk presented at the Typhoon-HIL exhibit at APEC 2016 his Cuk-buck 2 converter. First the critical salient waveforms are confirmed using Typhoon HIL latest 402 simulator, which has NO CONVERGENCE problems and offers dynamic ON SITE optimization of feedback control loop using Hardware in Loop (HIL) concept. Dr. Cuk showed that conventional synchronous buck is bad for any large step-down and especially for 48V to 1 V promoted by GaN device manufacturers as the next big thing!? This SHOOTOUT and explanations by Dr. Cuk confirm without the doubt that Cukbuck2 wins handily! More importantly this is just one in a number of new converter topologies that Dr. Cuk is now introducing which confirm that topology comes FIRST and DEVICES come second and must absorb all the bad properties of the converter such a buck which is patently bad for large voltage step-down. Buck converter might be tolerated for 10% voltage step-down or no step-down but NOT for large step-down. See for yourself the explanations by Dr. Cuk and look for related two part video of his seminar presentation at APEC 2016 Typhoon seminar and related technical paper posted on teslaco.com webpage and You Tube channel of Dr. Cuk.

TYPHOON SEMINAR by Dr. Ćuk at APEC 2016-ĆUK-BUCK2 TOPOLOGY BEST FOR ALL SWITCHING DEVICES! Part 2-

Publicado em 3 de abr de 2016 
This is the Part 2 of the Typhoon seminar by Dr. Ćuk at APEC 2016: WHAT COMES FIRST: DEVICES OR TOPOLOGY?, which answered clearly that the CONVERTER TOPOLOGY is by far the most important as switching devices GOOD or BAD performance depends EXCLUSIVELY and SOLELY on the converter topology used and not on SWITCHING DEVICES used! The conventional synchronous buck converter is compared to Ćuk-buck2 converter for 48V to 1 V conversion to demonstrate the point! The waveforms generated on the site by Typhoon-HIL simulator for Ćuk-buck2 converter confirm that synchronous buck converter is patently unsuitable for large voltage conversion step-downs irrespective of the device technology (yes, including the GaN devices, too!) due to extremely bad utilization of the switches! Synchronous rectifier switch needed in buck converter is rated for 100 V, 100 A or 10kW! Ćuk-buck2 converter uses only 2 V, 100 A rated device or 200 W. In addition, that switch turns-ON and turns-OFF at ZERO current compared to 100 A of the synchronous buck. Even magnetics is four times reduced! CONVERTER TOPOLOGIES DO MATTER!
