This paper presents a detailed analysis of operation principle for AHB Flyback converter. With the ability of ZVS operation for primary-side switches over wide operation range, this topology is a good candidate for high efficiency design as the switching loss can be greatly reduced. A straightforward design procedure is proposed with PFC as front stage for high power chargers and adapters. With Infineon’s latest CoolMOS technology and AHB controller, the whole system efficiency can reach 94% at 140W(28V/5A) under 90Vac.
