LLC transformerPrecision, Inc. announced the global launch of its new LLC transformer which is asserted to provide up to 99 percent efficiency and extremely low power loss. The technology combines two discrete components – a resonant inductor and transformer – into a single package reducing real estate up to 50 percent, according to the company. The Precision LLC transformer is 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. 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.  The company asserts that power dissipation can be lowered to as little as 5 percent, ensuring 99 percent transformer efficiency and 95 percent overall efficiency.
