New High Efficiency LLC Transformer at CDI

CDI, Precision Incorporated
Precision’s New High Efficiency LLC Transformer
Provides Up To 99% Efficiency
And 50% Real Estate Saving
Precision LLC Transformer

CDI announces the global launch of Precision, Inc’s new LLC transformer which provides up to 99% efficiency and extremely low power loss. The technology combines two discrete components – a resonant inductor and transformer – into a single package reducing costs by as much as 75% and real estate up to 50%.

LLC Transformer Applications:
The Precision LLC transformer is ideally suited for use in converters for a wide range of efficiency-sensitive applications

  • LED
  • LCD Televisions
  • industrial LED lighting
  • AC/DC power converter with a PFC front end

The LLC transformer is a key component in determining the efficiency of an LLC resonant converter. A resonant power conversion topology minimizes switching losses by promoting zero voltage switching (ZVS), minimizing unnecessary power dissipation in switches. Power dissipation can be lowered to as little as 5%, ensuring 99% transformer efficiency and 95% overall efficiency.

Precision’s experienced engineers study the LLC transformer design to obtain the correct leakage inductance through bobbin and litz wire optimizations. Their expertise in this area can be applied to each unique application to reduce transformer losses and costs by as much as 30%. This combination ensures that Precision customers can get the most optimized product, in the shortest amount of time.

The LLC transformer is the heart of a converter’s operation and any delay in delivery can add weeks or months to the design cycle. Time to market is minimized as the design is optimized from the beginning, eliminating the need for design reiterations.

LLC Transformer Features:
  • Standard and custom LLC transformers available
  • Power ranges of standard packages are between 100 to 800W
  • High power custom designs available
