ClassEgg®

High-Power boost PFC + LLC Resonant AC/DC Converter

ClassEgg® is the EcoVoltas architecture for high-power applications that require Power Factor Correction (PFC).

ClassEgg is a proprietary Zero Voltage Switching boost PFC + resonant LLC architecture that has been designed to offer dual regulated outputs and the best efficiency over the entire span of loads, offering a total peak efficiency of >95%, high power density and reduced BOM.

ClassEgg is best suited for high-efficiency PSUs for home appliances, TV panels, servers, computers, and a wide range of applications in consumer, industrial and appliance domains.
