LLC Transformers

The heart of your high frequency power solution

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. Combines enhanced performance with cost and real estate savings.

Features:

Reduces costs by as much as 75% and real estate up to 50%
99% transformer efficiency and 95% overall efficiency
Reduces transformer losses and costs by as much as 30%
Power ranges on standard packages from 100 to 800W. High powered custom LLC transformer designs available upon request.
Perfect for LED and LCD televisions, LED lightning, and all AC/DC power converters with a PFC front end
High power custom designs are also available
