LLC Transformer provides up to 99% efficiency.

March 19, 2013 - Combining resonant inductor and transformer into single package, LLC Transformer is available in power ranges from 100–800 W. Resonant power conversion topology minimizes switching losses by promoting zero voltage switching, minimizing unnecessary power dissipation in switches. Power dissipation can be lowered to as little as 5%, ensuring 99% transformer efficiency and 95% overall efficiency. Applications include LED/LCD TVs, industrial LED lighting, and AC/DC power converters with PFC front end.

Minneapolis, MN, 55430, USA

PROVIDES UP TO 99% EFFICIENCY AND 50% REAL ESTATE SAVINGS

Market-leading technical support, product performance optimization, fast turnaround

MINNEAPOLIS, MN – Precision, Inc. (www.precision-inc.com) announces the global launch of its 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%.

The Precision LLC transformer is ideally suited for use in converters for a wide range of efficiency-sensitive applications including LED and LCD televisions, industrial LED lighting and any AC/DC power converter with a PFC front end.

“As Energy Star tightens specifications for consumer products, the Precision LLC transformer is ideally suited to ensure maximum efficiency,” explained Welly Chou, Product Technology Manager at Precision. “Precision has combined a highly-efficient and highly-engineered product with market-leading technical support to offer customers significant cost savings and performance enhancements.”

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 supports the company´s new high performance LLC transformer with market-leading technical support. 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%.

Precision´s expert technical support is enhanced by the company´s extensive stock of litz wire and bobbins. 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. Samples of the Precision LLC transformer can be provided in as little as three days depending on design complexity, speeding time to market. Time to market is also minimized as the design is optimized from the beginning, eliminating the need for design reiterations.  

Precision offers both standard and custom LLC transformers. The power ranges of standard packages are between 100 and 800W. High power custom designs are also available. Lead times are as short as three days for samples and as little as 6-8 weeks for production quantities (dependent on technology complexity).
